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.

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 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.

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.

* elf/pic is disabled OR
  elf/pic enabled + callee is in module + callee has
  visibility protected or hidden

* 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.

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.

llvm-svn: 22886
 2005-08-18 23:53:15 +00:00
Nate Begeman 8a0933608a First round of support for doing scalar FP using the SSE2 ISA extension and 
XMM registers.  There are many known deficiencies and fixmes, which will be
addressed ASAP.  The major benefit of this work is that it will allow the
LLVM register allocator to allocate FP registers across basic blocks.

The x86 backend will still default to x87 style FP.  To enable this work,
you must pass -enable-sse-scalar-fp and either -sse2 or -sse3 to llc.

An example before and after would be for:
double foo(double *P) { double Sum = 0; int i; for (i = 0; i < 1000; ++i)
                        Sum += P[i]; return Sum; }

The inner loop looks like the following:
x87:
.LBB_foo_1:     # no_exit
        fldl (%esp)
        faddl (%eax,%ecx,8)
        fstpl (%esp)
        incl %ecx
        cmpl $1000, %ecx
        #FP_REG_KILL
        jne .LBB_foo_1  # no_exit

SSE2:
        addsd (%eax,%ecx,8), %xmm0
        incl %ecx
        cmpl $1000, %ecx
        #FP_REG_KILL
        jne .LBB_foo_1  # no_exit

the interest of not breaking things any more than they already are, I'm going
to leave the constant alone.
