Dale Johannesen ce97d55ad9 The hasMemory argument is irrelevant to how the argument
for an "i" constraint should get lowered; PR 6309.  While
this argument was passed around a lot, this is the only
place it was used, so it goes away from a lot of other
places.

Jim Grosbach ba3ece6f27 IT instructions are considered to be scheduling hazards, but are scheduled
with the following instructions. This is done via trickery by considering the
instruction preceding the IT to be the hazard. Care must be taken to ensure
it's the first non-debug instruction, or the presence of debug info will
affect codegen.

Part of the continuing work for rdar://7797940, making ARM code-gen unaffected
by the presence of debug information.

Dale Johannesen 5ad5226c58 Disallow matching "i" constraint to symbol addresses when
address requires a register or secondary load to compute
(most PIC modes).  This improves "g" constraint handling.  8015842.

The test from 2007 is attempting to test the fix for PR1761,
but since -relocation-model=static doesn't work on Darwin
x86-64, it was not testing what it was supposed to be testing
and was passing erroneously.  Fixed to use Linux x86-64.

Bill Wendling f470747a36 We are missing opportunites to use ldm. Take code like this:
void t(int *cp0, int *cp1, int *dp, int fmd) {
  int c0, c1, d0, d1, d2, d3;
  c0 = (*cp0++ & 0xffff) | ((*cp1++ << 16) & 0xffff0000);
  c1 = (*cp0++ & 0xffff) | ((*cp1++ << 16) & 0xffff0000);
  /* ... */
}

It code gens into something pretty bad. But with this change (analogous to the
X86 back-end), it will use ldm and generate few instructions.

Dale Johannesen d24c66b4a3 Do not do tail calls to external symbols. If the
branch turns out to be ARM-to-Thumb or vice versa
the linker cannot resolve this.  8120438.

If this optimization is going to be useful we probably
need a compiler flag "assume callees are same architecture"
or something like that.
