Reid Spencer 650d292f89 For PR761:

Evan Cheng 97057f37a5 - Target PIC style is no longer affected by relocation model.
- In x86-64 mode, symbols with external linkage (not just symbols which are
  defined externally) requires GOT indirect reference.
- Stylistic code clean up.

Reid Spencer c050af9126 Clean up some code around the store V, (cast P) -> store (cast V), P
transform. Change some variable names so it is clear what is source and
what is dest of the cast. Also, add an assert to ensure that the integer
to integer case is asserting if the bitwidths are different. This prevents
illegal casts from being formed and catches bitwidth bugs sooner.

2007-01-18 18:14:49 +00:00
Reid Spencer 726b68bc6e Fix a regression in the last patch. When constructing a BitMask, be careful
not to overflow 64-bits and end up with a 0 mask. This caused i64 values to
always be stored as 0 with lots of consequential damage to nightly test.

2007-01-18 07:34:57 +00:00
Reid Spencer 2867a1d466 Provide an isPowerOf2ByteWidth method for the IntegerType class. This will
mostly be used by back ends that wish to distinguish between integer types
that fit evenly within a natural integer type and those that don't.

Bill Wendling a341fab0af The zerofill directive needs a newline after it.

Reid Spencer f854f95a17 Use the new maskToBitWidth function to ensure that the results of
computations do not overflow the intended bit width.

llvm-svn: 33326
2007-01-18 02:12:51 +00:00
Reid Spencer 10fe0e0d48 Add an inline helper function that masks a GenericValue to a specified
bit width.

Reid Spencer 300e7fcb55 Make shl instruction mask its result to the correct bitsize. This is
sufficient to get llvm-test/SingleSource/UnitTests/Integer/general-test.ll
working with lli in interpreter mode.

llvm-svn: 33321
2007-01-18 01:32:46 +00:00
Reid Spencer fab44b682e Two changes:
1. Fix logic for executeGEP. Only 32-bit and 64-bit integer types are
   acceptable as indices.
2. Ensure that all integer cast operations truncate their result to the
   integer size of the operand.

llvm-svn: 33318

Reid Spencer 01f7e06d8f Make sure we truncate stored values to their bit width.

Chris Lattner c1ea85b4c4 Modify emission of jump tables on darwin to emit an extra "l" label that
delimits the boundaries of jump tables.  This lets the linker's dead code
stripping optimization do a better job.

llvm-svn: 33315
2007-01-18 01:15:58 +00:00
Chris Lattner 0ee2d46cfe add new JumpTableSpecialLabelPrefix hook to asmprinter for jumptable emission.

Reid Spencer 7300651384 For PR1028:
Add the llvm.stacksave and llvm.stackrestore intrinsics that correspond
to the GCC builtins __builtin_stack_save and __builtin_stack_restore. This
allows the CBE to execute these builtins, and fixes:

   test/CodeGen/CBackend/2007-01-17-StackSaveNRestore.ll
   External/SPEC/CINT2000/176.gcc (CBE)

Patch by Gordon Henriksen.

Reid Spencer 062a3b8241 For PR1028:
Ensure the CBE generates calls to GCC builtins for stack_save and
stack_restore when it encounters the corresponding intrinsics.

Patch by Gordon Henriksen.

writers.

Reid Spencer e7b24afae1 For PR739:
Support overriding the prefix and DESTDIR variables from the make command
line. This makes the makefile system a little more GNU compliant and the
feature makes it easier for distribution builders to re-target the install
location of LLVM.

llvm-svn: 33300
2007-01-17 10:40:54 +00:00
Anton Korobeynikov 3f6d52834b * Fix one more bug in PIC codegen: extra load is needed for *all*
non-statics.
* Introduce new option to output zero-initialized data to .bss section.
This can reduce size of binaries. Enable it by default for ELF &
Cygwin/Mingw targets. Probably, Darwin should be also added.
