Duncan Sands 75bc2250ca Fix some confusion in the Ada f-e build instructions between 
building without optimization and building with checking.

llvm-svn: 70205
 2009-04-27 11:21:35 +00:00
Sanjiv Gupta 1f8555a07f Now that any size of integer indices are allowed for sequential types, remove the unneccessary gyan about promoting them. 
llvm-svn: 70181
 2009-04-27 03:21:00 +00:00
Chris Lattner a6fdf5a8c9 Add two new record types to the blockinfo block: 
BLOCKNAME and SETRECORDNAME.  This allows a bitcode
file to be self describing with pretty names for 
records and blocks in addition to numbers.  This
enhances llvm-bcanalyzer to use this to print prettily.

llvm-svn: 70165
 2009-04-26 22:21:57 +00:00
Sanjiv Gupta 8d319047c5 Any size of integral indices are allowed in gep for indexing into sequential types. Also adding a test case to check the indices type allowed into struct.

 2009-04-23 21:27:58 +00:00
David Greene 196ac3c69a Make BinOps typed and require a type specifier for !nameconcat. This 
allows binops to be used in typed contexts such as when passing
arguments to classes.

Chris Lattner 184f1be4a8 Add a new "available_externally" linkage type. This is intended 
to support C99 inline, GNU extern inline, etc.  Related bugzilla's
include PR3517, PR3100, & PR2933.  Nothing uses this yet, but it
appears to work.

Chris Lattner 4bda28e765 add a new Blob encoding abbreviation for bitcode files that emits 
elements in a form that is efficient for the reader to just get a
pointer in memory and start reading.  APIs to do efficient reading

Constant, MDString and MDNode which can only be used by globals with a name
that starts with "llvm." or as arguments to a function with the same naming
restriction.

Duncan Sands 12da8ce3d2 Introduce new linkage types linkonce_odr, weak_odr, common_odr 
and extern_weak_odr.  These are the same as the non-odr versions,
except that they indicate that the global will only be overridden
by an *equivalent* global.  In C, a function with weak linkage can
be overridden by a function which behaves completely differently.
This means that IP passes have to skip weak functions, since any
deductions made from the function definition might be wrong, since
the definition could be replaced by something completely different
at link time.   This is not allowed in C++, thanks to the ODR
(One-Definition-Rule): if a function is replaced by another at
link-time, then the new function must be the same as the original
function.  If a language knows that a function or other global can
only be overridden by an equivalent global, it can give it the
weak_odr linkage type, and the optimizers will understand that it
is alright to make deductions based on the function body.  The
code generators on the other hand map weak and weak_odr linkage
to the same thing.

Devang Patel c094970cd2 Each input file is encoded as a separate compile unit in LLVM debugging 
information output. However, many target specific tool chains prefer to encode
only one compile unit in an object file. In this situation, the LLVM code
generator will include  debugging information entities in the compile unit 
that is marked as main compile unit. The code generator accepts maximum one main
compile unit per module. If a module does not contain any main compile unit 
then the code generator will emit multiple compile units in the output object 
file.

[Part 1]

Update DebugInfo APIs to accept optional boolean value while creating DICompileUnit  to mark the unit as "main" unit. By defaults all units are considered  non-main.  Update SourceLevelDebugging.html to document "main" compile unit.

Update DebugInfo APIs to not accept and encode separate source file/directory entries while creating various llvm.dbg.* entities. There was a recent, yet to be documented, change to include this additional information so no documentation changes are required here.

Update DwarfDebug to handle "main" compile unit. If "main" compile unit is seen then all DIEs are inserted into "main" compile unit. All other compile units are used to find source location for llvm.dbg.* values. If there is not any "main" compile unit then create unique compile unit DIEs for each llvm.dbg.compile_unit.

[Part 2]

Create separate llvm.dbg.compile_unit for each input file. Mark compile unit create for main_input_filename as "main" compile unit. Use appropriate compile unit, based on source location information collected from the tree node, while creating llvm.dbg.* values using DebugInfo APIs.

The problematic part of this patch is that we were out of attribute bits,

Nick Lewycky ddffe620e4 Introducing nocapture, a parameter attribute for pointers to indicate that the 
callee will not introduce any new aliases of that pointer.

The attributes had all bits allocated already, so I decided to collapse
alignment. Alignment was previously stored as a 16-bit integer from bits 16 to
32 of the attribute, but it was required to be a power of 2. Now it's stored in
log2 encoded form in five bits from 16 to 21. That gives us 11 more bits of
space.

You may have already noticed that you only need four bits to encode a 16-bit
power of two, so why five bits? Because the AsmParser accepted 32-bit
alignments, even though we couldn't store them (they were silently discarded).
Now we can store them in memory, but not in the bitcode.

The bitcode format was already storing these as 64-bit VBR integers. So, the
bitcode format stays the same, keeping the alignment values stored as 16 bit
raw values. There's some hideous code in the reader and writer that deals with
this, waiting to be ripped out the moment we run out of bits again and have to
replace the parameter attributes table encoding.
