Evan Cheng 5e5a63cf8f CodeGen still defaults to non-verbose asm, but llc now overrides it and default to verbose. 
llvm-svn: 67668
 2009-03-25 01:47:28 +00:00
Mon P Wang f67448adf8 Added option to enable generating less precise mad (multiply addition) 
for those architectures that support the instruction.

llvm-svn: 67363
 2009-03-20 05:06:58 +00:00
Bill Wendling 42adc73a2b Add a -no-implicit-float flag. This acts like -soft-float, but may generate 
floating point instructions that are explicitly specified by the user.

Dan Gohman 75cee3a93c Enable the red zone on x86-64 by default.

 2009-01-27 00:58:47 +00:00
Dan Gohman b6d36e1d14 Implement Red Zone utilization on x86-64. This is currently 
disabled by default; I'll enable it when I hook it up with
the llvm-gcc flag which controls it.

llvm-svn: 63056
 2009-01-26 22:22:31 +00:00
Dan Gohman 9c4b7d5c4f Fix command-line option printing to print two spaces where needed, 
instead of requiring all "short description" strings to begin with
two spaces. This makes these strings less mysterious, and it fixes
some cases where short description strings mistakenly did not
begin with two spaces.

llvm-svn: 57521
 2008-10-14 20:25:08 +00:00
Owen Anderson 1d338fc6a4 Add an option to enable StrongPHIElimination, for ease of testing. 
llvm-svn: 57259

Owen Anderson bbeb8f0807 This option doesn't need to be a target option. It can be in SDISel instead.

Owen Anderson a102290bdc - Fix SelectionDAG to generate correct CFGs. 
- Add a basic machine-level dead block eliminator.

These two have to go together, since many other parts of the code generator are unable to handle the unreachable blocks otherwise created.

Dale Johannesen c31eb205c1 Add a flag to disable jump table generation (all 
switches use the binary search algorithm) for
environments that don't support it.  PPC64 JIT
is such an environment; turn the flag on for that.

Dan Gohman d78c400b5b Clean up the use of static and anonymous namespaces. This turned up 
several things that were neither in an anonymous namespace nor static
but not intended to be global.

Dale Johannesen 876224b1e8 Reverse sense of unwind-tables option. This means 
stack tracebacks on Darwin x86-64 won't work by default;
nevertheless, everybody but me thinks this is a good idea.

llvm-svn: 49663
 2008-04-14 17:54:17 +00:00
Dale Johannesen 4c0c018bc5 Rename -disable-required-unwind-tables to unwind-tables-optional.

 2008-04-08 18:07:49 +00:00
Dale Johannesen 344aec2952 Implement new llc flag -disable-required-unwind-tables. 
Corresponds to -fno-unwind-tables (usually default in gcc).

Arnold Schwaighofer 9ccea99165 Added tail call optimization to the x86 back end. It can be 
enabled by passing -tailcallopt to llc.  The optimization is
performed if the following conditions are satisfied:
* caller/callee are fastcc
* elf/pic is disabled OR
  elf/pic enabled + callee is in module + callee has
  visibility protected or hidden

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: 28437
 2006-05-23 18:18:46 +00:00
Evan Cheng ea1450742e Added option -enable-finite-only-fp-math. When on, the codegen can assume that 
FP arithmetic arguments and results are never NaNs or +=Infs. This includes
ignoring parity flag (PF) when checking for FP equality.

Owen Anderson 20a631fde7 Refactor TargetMachine, pushing handling of TargetData into the target-specific subclasses. This has one caller-visible change: getTargetData() now returns a pointer instead of a reference. 
This fixes PR 759.
