Reid Spencer 5041bdba19 Re-apply last (reverted) patch. Reverting doesn't solve the actual problem 
and creates issues on other platforms like Cygwin and MingW.

Jeff Cohen c3d0ae2e48 Don't quote the PATH variable value just in case it has spaces in it, as 
it breaks "gmake check".

Chris Lattner 82787e90f3 This hunk: 
-  unsigned TrueValue = getReg(TrueVal, BB, BB->begin());
+  unsigned TrueValue = getReg(TrueVal);

Fixes the PPC regressions from last night.

The other hunk is just a clarity improvement.

Reid Spencer 34982d8dc8 Avoid use of -fomit-frame-pointer on FreeBSD platforms. It causes thrown 
exceptions to abort() in cases where it should not.

Many thanks to Duraid Madina for doing the heavy lifting on the analysis
of this problem.

Jeff Cohen 2cf40e142c Eliminate the use of the global variable hack in the X86 target that was used 
to get Visual Studio to link in X86.lib to the executables that need it.  There
is another way of doing it.

Chris Lattner 733aac1270 Disable 2->3 address promotion of add and inc instructions to LEA's. In 
addition to being three address, LEA's don't set the flags.

This fixes 186.crafty.

Chris Lattner 295e45e60e Two changes here: 
1. Add new instructions for checking parity flags: JP, JNP, SETP, SETNP.
2. Set the isCommutable and isPromotableTo3Address bits on several
   instructions.

llvm-svn: 19246
 2005-01-02 02:35:46 +00:00
Chris Lattner 9590870a0d Make the 2-address instruction lowering pass smarter in two ways: 
1. If we are two-addressing a commutable instruction and the LHS is not the
   last use of the variable, see if the instruction is the last use of the
   RHS.  If so, commute the instruction, allowing us to avoid a
   register-register copy in many cases for common instructions like ADD, OR,
   AND, etc on X86.
2. If #1 doesn't hold, and if this is an instruction that also existing in
   3-address form, promote the instruction to a 3-address instruction to
   avoid the register-register copy.  We can do this for several common
   instructions in X86, including ADDrr, INC, DEC, etc.

This patch implements test/Regression/CodeGen/X86/commute-two-addr.ll,
overlap-add.ll, and overlap-shift.ll when I check in the X86 support for it.
