On powerpc64le, modifying the way combine treats function parameters
and call arguments results in some regressions.
For instance, this testcase from varasm.c
extern int foo3 (void *, ...);
extern void foo4 (void *, const char *);
int
emit_tls_common (void *decl,
const char *name

Well that didn't last very long. There are regressions, and just from
looking at disassembled object files it would appear to be frame
pointer related. So the sim

The rlwinm vs. rldicl change was in dwarf2out.c add_ranges_num for r3
one insn before a blr. I'm sure that was due to no

This stops combine messing with parameter and return value copies
from/to hard registers. Bootstrapped and regression tested
powerpc64le-linux, powerpc64-linux and x86_64-linux. In looking at a
number of different powerpc64le gcc/*.o files, I noticed a few code
generation improvements. There wer
