20 years agoAdd support to the local allocator for fusing spill code into the instructions
Chris Lattner [Tue, 17 Feb 2004 08:09:40 +0000 (08:09 +0000)]
Add support to the local allocator for fusing spill code into the instructions
that need them.  This is very useful on CISCy targets like the X86 because it
reduces the total spill pressure, and makes better use of it's (large)
instruction set.  Though the X86 backend doesn't know how to rewrite many
instructions yet, this already makes a substantial difference on 176.gcc for
example:

Before:
Time:
   8.0099 ( 31.2%)   0.0100 ( 12.5%)   8.0199 ( 31.2%)   7.7186 ( 30.0%)  Local Register Allocator

Code quality:
734559 asm-printer           - Number of machine instrs printed
111395 ra-local              - Number of registers reloaded
 79902 ra-local              - Number of registers spilled
231554 x86-peephole          - Number of peephole optimization performed

After:
Time:
   7.8700 ( 30.6%)   0.0099 ( 19.9%)   7.8800 ( 30.6%)   7.7892 ( 30.2%)  Local Register Allocator
Code quality:
733083 asm-printer           - Number of machine instrs printed
  2379 ra-local              - Number of reloads fused into instructions
109046 ra-local              - Number of registers reloaded
 79881 ra-local              - Number of registers spilled
230658 x86-peephole          - Number of peephole optimization performed

So by fusing 2300 instructions, we reduced the  static number of instructions
by 1500, and reduces the number of peepholes (and thus the work) by about 900.
This also clearly reduces the number of reload/spill instructions that are
emitted.

Now that the lowerinvoke pass inserts calls to llvm.setjmp/llvm.longjmp, some
hacks can be banished.  Also, this gives us the opportunity to emit special code
for the setjmp/longjmps which alows the elimination of one GCC warning for every
setjmp/longjmp site (which is often THOUSANDS in C++ programs).  Yaay!
