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

Bill Wendling e750f61ac5 Have the OutputBuffer take the is64Bit and isLittleEndian booleans.

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.

 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.

Bill Wendling cd9c1f035a Changed to use the OutputBuffer instead of the methods in MachO and ELF 
writers.

llvm-svn: 33311
 2007-01-17 22:22:31 +00:00
Bill Wendling cbb5501c5d Refactored output buffer methods from MachO and ELF writers.

Devang Patel dffca63396 Update assignPassManager() signature to allow selection of preferred 
pass manager type. This allows new FPPassManager to select Call Graph
Pass Manager (if available) as its parent.

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.

Chris Lattner f64cc9edd1 restructure code a bit to make use of continue (simplifying things). Generalize 
the .zerofill directive emission to not be darwin-specific

Anton Korobeynikov 716efbfc63 Document flag 
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.

llvm-svn: 33287
 2007-01-17 03:47:54 +00:00
Bill Wendling f758157385 New "TargetObjInfo" class. This holds information that the object writers will 
use to write things to the file. It's abstract so each target should implement
its own version for each writer type.

Reid Spencer c35fec9567 Fix this tool for use on Darwin which requires the file to come after the 
commands. Linux is more forgiving.

Reid Spencer 082a77f1c9 For PR1117: 
Make the assembler generate a nice error message if a bad cast instruction
is attempted instead of asserting out. This is made possible by the
recently exposed method CastInst::castIsValid() which checks the validity
of any cast instruction.
