Brian Gaeke a730103518 Add a warning about not "new"ing or "delete"ing CallSites 
llvm-svn: 9782
 2003-11-07 19:25:22 +00:00
Misha Brukman d3af61d883 Added ability to register FunctionPasses as optimizations, with 
TargetMachine-accepting constructors (thanks to Chris).

llvm-svn: 9781
 2003-11-07 18:56:32 +00:00
Misha Brukman 7120c837fb Make the page footer consistent with the rest of the site. 
llvm-svn: 9779
 2003-11-07 18:11:14 +00:00
Misha Brukman 2c3068026a Switch to emitting MachineConstantPool the way it was meant to be done. 
llvm-svn: 9777
 2003-11-07 18:06:26 +00:00
Misha Brukman 2133b0513d Switch to using the standard representation of the constant pool -- namely, the 
MachineConstantPool. This involved refactoring the two classes involved in
printing out Sparc assembly. In fact, they should share all this code anyway.

llvm-svn: 9776
 2003-11-07 17:45:28 +00:00
Misha Brukman faa42d264f We accept TargetMachine as a const reference. 
llvm-svn: 9775
 2003-11-07 17:44:18 +00:00
Misha Brukman bd4a8ed139 PreSelection and PeepholeOpts are now FunctionPasses. 
llvm-svn: 9774
 2003-11-07 17:43:43 +00:00
Misha Brukman 81c748c1e2 * Stop making a global for each constant that cannot live in an instruction; 
it will be converted to a MachineConstantPool index during instruction
  selection
* This is now eligible to become a FunctionPass since it does not have any side
  effects outside of the function it is processing.

llvm-svn: 9773
 2003-11-07 17:31:22 +00:00
Misha Brukman bf9ed7ac1f * Use the MachineConstantPool for storing constants instead of a hash_set; 
* Do not create new globals for constants!

Also, order #includes as per coding style guide

 2003-11-05 22:13:10 +00:00
Brian Gaeke 1d9515b0a1 Do not assume the first file is a bytecode file. Instead, construct a dummy 
Module and link things into that.

Also, fix a typo in an error message.

llvm-svn: 9748
 2003-11-05 22:13:00 +00:00
Brian Gaeke 31af708ef6 Shorten and correct some function-header comments. 
Make "verbose" output MUCH nicer. Now it tells you when you are linking a
bytecode file, or an archive, and whether it's because you called it by name,
or because you gave it a -l option, and it says "Trying" before it takes
action and prints a message in the past tense afterwards.

Make LinkFiles not skip the first file in Files.

Make LinkFiles warn you if it can't find a file and LLVM_LIB_SEARCH_PATH is
unset.

llvm-svn: 9746
 2003-11-05 22:06:03 +00:00
Chris Lattner 4e1b467594 Fix the problem with running cleanups in bugpoint: We were deleting arguments 
of intrinsic functions, causing the verifier to fail.

llvm-svn: 9745
 2003-11-05 21:53:41 +00:00
Chris Lattner a616c55ba9 Bugpoint no longer has this option 
llvm-svn: 9744
 2003-11-05 21:46:13 +00:00
Chris Lattner 2920100e4d I hate it when bugpoint is all ready to give me a bytecode file, then crashes 
in final cleanups.  Then you had to run the whole mess again with
-disable-final-cleanups.

This makes bugpoint run the cleanups in a protected environment so that if
they crash, bugpoint itself doesn't crash.  This makes things much happier,
implements a FIXME, and gets rid of YABPO (yet another bugpoint option).

Alkis Evlogimenos 20d03bb166 Update documentation since it was misleading: make it clear that a 
negative instruction count is returned if instructions are removed
from a basic block.

llvm-svn: 9705
 2003-11-04 23:07:00 +00:00
Alkis Evlogimenos 9118a426d3 Change all machine basic block modifier functions in MRegisterInfo to 
return the number of instructions added to/removed from the basic block
passed as their first argument.

Note: This is only needed because we use a std::vector instead of an
ilist to keep MachineBasicBlock instructions. Inserting an instruction
to a MachineBasicBlock invalidates all iterators to the basic
block. The return value can be used to update an index to the machine
basic block instruction vector and circumvent the iterator elimination
problem but this is really not needed if we move to a better
representation.

Added assert() to ensure symbol table is well formed.
Added code to remember the value that was found; resolving types can change

Added comments to the ResolveTypes() function (mainly for my own benefit).
Please feel free to correct the comments if they are not accurate.

Chris Lattner 2b9926fc8e All DSGraphs keep a reference to the targetdata they are created with. This is 
used to eliminate the hard coded, hacked in, sparc specific, global TargetData.

eliminates a crash.

Chris Lattner 0658cc20bd Make this pass substantially stronger by having it delete dead return values 
as well as arguments.  Now it can delete arguments and return values which are
only passed into other arguments or are returned, if they are dead.  This causes
it to delete several hundred extra args/retvals from the C++ hello world program,
shrinking it by about 2K.

Chris Lattner 2d9c117e21 Reorder for minor efficiency gain 
llvm-svn: 9285
 2003-10-20 05:54:26 +00:00
Chris Lattner 6acb1bedb1 Emit x86 instructions for: A = B op C, where A and B are 16-bit registers, 
C is a constant which can be sign-extended from 8 bits without value loss,
and op is one of: add, sub, imul, and, or, xor.

This allows the JIT to emit the one byte version of the constant instead of
the two or 4 byte version.  Because these instructions are very common, this
can save a LOT of code space.  For example, I sampled two benchmarks, 176.gcc
and 254.gap.

BM        Old     New    Reduction
176.gcc 2673621 2548962  4.89%
254.gap  498261  475104  4.87%

Note that while the percentage is not spectacular, this did eliminate
124.6 _KILOBYTES_ of codespace from gcc.  Not bad.

Note that this doesn't effect the llc version at all, because the assembler
already does this optimization.
