Evan Cheng 2dbffa4e76 Add pseudo dependency to force two-address instruction to be scheduled after

Evan Cheng 66298e226f There are times when the coalescer would not coalesce away a copy but the copy 
can be eliminated by the allocator is the destination and source targets the
same register. The most common case is when the source and destination registers
are in different class. For example, on x86 mov32to32_ targets GR32_ which
contains a subset of the registers in GR32.

The allocator can do 2 things:
1. Set the preferred allocation for the destination of a copy to that of its source.
2. After allocation is done, change the allocation of a copy destination (if
   legal) so the copy can be eliminated.

This eliminates 443 extra moves from 403.gcc.

 2007-10-29 20:44:42 +00:00
Evan Cheng e106e2f142 Enable more fold (sext (load x)) -> (sext (truncate (sextload x))) 
transformation. Previously, it's restricted by ensuring the number of load uses
is one. Now the restriction is loosened up by allowing setcc uses to be
"extended" (e.g. setcc x, c, eq -> setcc sext(x), sext(c), eq).

Chris Lattner 5e99fd8c0d Add support for the x86-64 'q' regigster modifier, and add support for the 
b/h/w/k/q inline asm memory modifiers, which are just ignored.  This fixes
PR1748 and CodeGen/X86/2007-10-28-inlineasm-q-modifier.ll

Evan Cheng 7f3d02471d Loosen up iv reuse to allow reuse of the same stride but a larger type when truncating from the larger type to smaller type is free. 
e.g.

Evan Cheng 133694db06 If a loop termination compare instruction is the only use of its stride, 
and the compaison is against a constant value, try eliminate the stride
by moving the compare instruction to another stride and change its
constant operand accordingly. e.g.

loop:
...
v1 = v1 + 3
v2 = v2 + 1
if (v2 < 10) goto loop
=>
loop:
...
v1 = v1 + 3
if (v1 < 30) goto loop

Dale Johannesen 52bbe1b171 This was failing on Darwin, which defaults to PIC; 
no lea was generated.  I think this follows the intent.

llvm-svn: 43312
 2007-10-24 20:58:14 +00:00
Dan Gohman e0c3d9f338 Strength reduction improvements. 
- Avoid attempting stride-reuse in the case that there are users that
   aren't addresses. In that case, there will be places where the
   multiplications won't be folded away, so it's better to try to
   strength-reduce them.

 - Several SSE intrinsics have operands that strength-reduction can
   treat as addresses. The previous item makes this more visible, as
   any non-address use of an IV can inhibit stride-reuse.

 - Make ValidStride aware of whether there's likely to be a base
   register in the address computation. This prevents it from thinking
   that things like stride 9 are valid on x86 when the base register is
   already occupied.

Also, XFAIL the 2007-08-10-LEA16Use32.ll test; the new logic to avoid
stride-reuse elimintes the LEA in the loop, so the test is no longer
testing what it was intended to test.

llvm-svn: 43231
 2007-10-22 20:40:42 +00:00
Dan Gohman bf474959a3 Fix the folding of multiplication into addresses on x86, which was broken

Rafael Espindola 813a0b1d29 Test byval with a 8 bit aligned struct 
llvm-svn: 43173
 2007-10-19 11:29:21 +00:00
Rafael Espindola 846c19dd70 Add support for byval function whose argument is not 32 bit aligned. 
To do this it is necessary to add a "always inline" argument to the
memcpy node. For completeness I have also added this node to memmove
and memset.  I have also added getMem* functions, because the extra
argument makes it cumbersome to use getNode and because I get confused
by it :-)

llvm-svn: 43172
 2007-10-19 10:41:11 +00:00

Dan Gohman be37007e64 Add intrinsics for sin, cos, and pow. These use llvm_anyfloat_ty, and so

llvm-svn: 42885
 2007-10-12 00:01:22 +00:00

llvm-svn: 42878
 2007-10-11 23:04:36 +00:00
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

Rafael Espindola 6c04ac1db0 Refactor the memcpy lowering for the x86 target. 
The only generated code difference is that now we call memcpy when
the size of the array is unknown. This matches GCC behavior and is
better since the run time value can be arbitrarily large.

Dan Gohman 31599685c7 When both x/y and x%y are needed (x and y both scalar integer), compute 
both results with a single div or idiv instruction. This uses new X86ISD

so that the SelectionDAG's CSE can automatically eliminate redundant
computations.

a vector instruction is used for a scalar purpose, they can still require
the full vector alignment. And add a regression test for this.
