Chris Lattner 5e693ed07b Rip all of the global variable lowering logic out of TargetAsmInfo. Since
it is highly specific to the object file that will be generated in the end,
this introduces a new TargetLoweringObjectFile interface that is implemented
for each of ELF/MachO/COFF/Alpha/PIC16 and XCore.

Though still is still a brutal and ugly refactoring, this is a major step
towards goodness.

This patch also:
1. fixes a bunch of dangling pointer problems in the PIC16 backend.
2. disables the TargetLowering copy ctor which PIC16 was accidentally using.
3. gets us closer to xcore having its own crazy target section flags and
   pic16 not having to shadow sections with its own objects.
4. fixes wierdness where ELF targets would set CStringSection but not
   CStringSection_.  Factor the code better.
5. fixes some bugs in string lowering on ELF targets.

Chris Lattner e7cb8f7987 Sink getSectionPrefixForUniqueGlobal down into the TAI
implementations that need it, rearrange ELFTAI.

llvm-svn: 77236
2009-07-27 19:14:14 +00:00
Sean Callanan 5908cfedbb Many of Daniel's fixes.
I'm returning the number of bytes actually copied so that the client has some
warning when it reads past the end of the buffer.

I'm keeping the distinction between getByte() and getBytes() for now for
subclasses that use functions like ptrace() on Linux and only have a restricted
interface.  This makes their implementation easier, and subclasses can always
write a one-line implementation of readByte() that uses their custom 
readBytes().

Chris Lattner 149465ea06 Eliminate SectionFlags, just embed a SectionKind into Section

llvm-svn: 77184
2009-07-27 05:32:16 +00:00
Chris Lattner 602d44fa70 untangle a TargetAsmInfo hack where ELFTargetAsmInfo would create a
'unnamed' bss section, but some impls would want a named one.  Since
they don't have consistent behavior, just make each target do their
own thing, instead of doing something "sortof common" then having
targets change immutable objects later.

llvm-svn: 77165
2009-07-26 19:23:28 +00:00
Chris Lattner e3c374ac33 Use the RHS length instead of the LHS length. They are both the same,
but this ends up compiling code like this:

int foo(const StringRef &R) {
  return R == "food";
}

to use a constant sized memcmp instead of a variable memcmp.

Chris Lattner 1d68bd7f97 Rearrange all the SectionKinds and structure them into a hierarchical
group instead of a bunch of random unrelated ideas.  Provide predicates
to categorize a SectionKind into a group, and use them instead of 
getKind() throughout the code.

This also renames a ton of SectionKinds to be more consistent and
evocative, and adds a huge number of comments on the enums so that
I will hopefully be able to remember how this stuff works long from
now.

llvm-svn: 77114
2009-07-26 02:22:58 +00:00
Daniel Dunbar 47d679151b Add TargetRegistry::lookupTarget.
- This is a simplified mechanism which just looks up a target based on the
   target triple, with a few additional flags.

 - Remove getClosestStaticTargetForModule, the moral equivalent is now:
     lookupTarget(Mod->getTargetTriple, true, false, ...);

 - This no longer does the fuzzy matching with target data (based on endianness
   and pointer width) that getClosestStaticTargetForModule was doing, but this
   was deemed unnecessary.

Daniel Dunbar 987ec564e7 Remove Value::setName(const char*).
- Split into a separate patch because there is a slight functionality change,
   it is no longer valid to call setName(0), which was equivalent to
   setName(""). I'm hoping no one depends on this...

llvm-svn: 77099

2009-07-25 23:21:55 +00:00
Chris Lattner 60f3b73e11 this is (unfortunately) several changes mixed together:
1. Spell SectionFlags::Writeable as "Writable".
2. Add predicates for deriving SectionFlags from SectionKinds.
3. Sink ELF-specific getSectionPrefixForUniqueGlobal impl into
   ELFTargetAsmInfo.
4. Fix SectionFlagsForGlobal to know that BSS/ThreadBSS has the
   BSS bit set (the real fix for PR4619).
5. Fix isSuitableForBSS to not put globals with explicit sections
   set in BSS (which was the reason #4 wasn't fixed earlier).
6. Remove my previous hack for PR4619.

Daniel Dunbar 691a4784db Simplify JIT target selection.
- Instead of requiring targets to define a JIT quality match function, we just

   target which matches the triple and has a JIT.

Also, rewrite the associated def-use walking code to be non-recursive

Reid Kleckner 1a722d9b73 Make the JIT code emitter properly retry and ask for more memory when it runs
out of memory, and also make the default memory manager allocate more memory
when it runs out.

Also, switch function stubs and global data over to using the BumpPtrAllocator.

This makes it so the JIT no longer mmaps (or the equivalent on Windows) 16 MB
of memory, and instead allocates in 512K slabs.  I suspect this size could go
lower, especially on embedded platforms, now that more slabs can be allocated.

llvm-svn: 76828
2009-07-23 00:49:59 +00:00
Reid Kleckner 5bd6105d65 Parameterize the BumpPtrAllocator over a slab allocator. It defaults to using
malloc, so there should be no functional changes to other code.

These changes are necessary since I have plans to use this allocator in the JIT
memory manager, and it needs a special allocator.

I also added some tests which helped me pinpoint some bugs.

This is considered a workaround. The problem is some targets are not modeling side effects correctly. PPC is apparently one of those. This patch allows ppc llvm-gcc to bootstrap on Darwin. Once we find out which instruction definitions are wrong, we can remove the PPCInstrInfo workaround.

remove after evaluation. This is mostly useful for Objective-C metadata.

This is plumbing, so we don't have a use of it yet. More to come, etc.

Chris Lattner e79b2bc088 Untangle a snarl that I discovered when updating the mangler,
starting in getCurrentFunctionEHName.  Among other problems,
we would try to privative a "foo.eh" label, but end up emitting
the label as _Lfoo.eh instead of L_foo.eh on darwin.  This is really
bad, and the linker has always tolerated these labels existing.
For now, just emit them as _foo.eh.

This patch also fixes problems with ".eh" labels on unnamed
functions and eliminates two strangely defined TargetAsmInfo
hooks.

Jeffrey Yasskin efad8e45fe Add line numbers to OProfile. To do this, I added a processDebugLoc()
call to the MachineCodeEmitter interface and made copying the start
line of a function not conditional on whether we're emitting Dwarf
debug information. I'll propagate the processDebugLoc() calls to the
non-X86 targets in a followup patch.

In the long run, it'll probably be better to gather this information
through the DwarfWriter, but the DwarfWriter currently depends on the
AsmPrinter and TargetAsmInfo, and fixing that would be out of the way
for this patch.

There's a bug in OProfile 0.9.4 that makes it ignore line numbers for
addresses above 4G, and a patch fixing it at
http://thread.gmane.org/gmane.linux.oprofile/7634

Dan Gohman 5a347d4bb7 formatted_raw_ostream both is-a raw_ostream and has-a raw_ostream. This
means that two separate raw_ostreams are doing buffering before data is
sent to the underlying stream. Besides the inefficiency of redundant
buffering, the second level of buffering doesn't recieve flush()
requests.

Fix this by having formatted_raw_ostream set the underlying raw_ostream
to be unbuffered. This eliminates inefficiency due to redundant buffering,
and it makes the flush() disconnect harmless.

This fixes PR4559.

Dan Gohman 58fcef917c Change raw_ostream so that it doesn't call llvm_report_error
immediately on every output error. Instead, add a flag to
raw_ostream, and set the flag whenever an error is detected.

The flag can be queried and cleared from the public API. This
gives applications more flexibility to handling errors in
application-specific ways.

If the flag is not cleared when the raw_ostream is destructed,
llvm_report_error is called from the destructor. This ensures
that errors are not implicitly silenced, and provides
convenient default behavior for tools like llc and opt.
Clients wishing to avoid llvm_report_error calls from
raw_ostream should check for errors and clear the error flag.

Daniel Dunbar 078a71e4a9 Add new TargetRegistry.
Targets implement a single global Target structure which will live in a new
<Target>/TargetInfo library; this will be present in any image which the target
is usable in.
 - Optional target specific classes can then be registered and attached to the
   Target description.

 - Registration for normal Targets will be done via the initialization functions
   instead of using static constructors.

 - This allows clients to use a single interface to obtain target data, without
   requiring the code generator be linked in. It also provides a natural
   extension point for adding new optional target data (assembler parser,
   disassembler, etc.).

 - This also provides a new entry point for obtaining a target for a particular
   triple (without a module).

 - Not yet used, however this should eventually replace the TargetMachineRegistry.

Chris Lattner 8c9a96b966 Reapply my previous asmprinter changes now with more testing and two
additional bug fixes:

1. The bug that everyone hit was a problem in the asmprinter where it
   would remove $stub but keep the L prefix on a name when emitting the
   indirect symbol.  This is easy to fix by keeping the name of the stub
   and the name of the symbol in a StringMap instead of just keeping a
   StringSet and trying to reconstruct it late.

2. There was a problem printing the personality function.  The current
   logic to print out the personality function from the DWARF information
   is a bit of a cesspool right now that duplicates a bunch of other 
   logic in the asm printer.  The short version of it is that it depends
   on emitting both the L and _ prefix for symbols (at least on darwin)
   and until I can untangle it, it is best to switch the mangler back to
   emitting both prefixes.

Chris Lattner 774f2a2d51 Change the X86 asmprinter to use the mangler to apply suffixes like "$non_lazy_ptr"
to symbols instead of doing it with "printSuffixedName".  This gets us to the point
where there is a real separation between computing a symbol name and printing it,
something I need for MC printer stuff.

This patch also fixes a corner case bug where unnamed private globals wouldn't get
the private label prefix.

Next up, rename all uses of getValueName -> getMangledName for better greppability,
and then tackle the ppc/arm backends to eliminate "printSuffixedName".

llvm-svn: 75609
2009-07-14 05:46:55 +00:00
Chris Lattner f34815b32f Change the internal interface to makeNameProper to take a bool that
indicates whether the label is private or not, instead of taking
prefix stuff.  One effect of this is that symbols will be generated
with *just* the private prefix, instead of both the private prefix
*and* the user-label-prefix, but this doesn't matter as long as it
is consistent.  For example we'll now get "Lfoo" instead of "L_foo".
These are just assembler temporary labels anyway, so they never even
make it into the .o file.

Dan Gohman 6f6d864815 Introduce a new LoopInfo utility function makeLoopInvariant, which
works similar to isLoopInvariant, except that it will do trivial
hoisting to try to make the value loop invariant if it isn't already.
This makes it easier for transformation passes to clear trivial
instructions out of the way (the regular LICM pass doesn't run
until relatively late). This is code factored out of LoopSimplify
and other places.

Chris Lattner 105efaf3df rename Memo/Count to AnonGlobalIDs/NextAnonGlobalID to be more
descriptive.  Thange them to keep track of the ID of a global that is
assigned, not the first mangled name returned for it.  Without doing this,
we are required to always use the same suffix for a global that gets 
mangled.  This means that we can mangle the same global once with $stub
and another time with $non_lazy_ptr or whatever.
