Create a stack frame on ARM when2010-02-24T22:43:17ZJakob Stoklund Olesenstoklund@2pi.dk2010-02-24T22:43:17Zurn:sha1:657baec0af38d84e24e4738b0696bb99d1517179
- Function uses all scratch registers AND
- Function does not use any callee saved registers AND
- Stack size is too big to address with immediate offsets.
In this case a register must be scavenged to calculate the address of a stack
object, and the scavenger needs a spare register or emergency spill slot.

LowerCall() should always do getCopyFromReg() to reference the stack pointer.2010-02-24T01:43:03ZJim Grosbachgrosbach@apple.com2010-02-24T01:43:03Zurn:sha1:f9a4b7653d2a838b344dc3cd38b37f7803059d79
Machine instruction selection is much happier when operands are in virtual
registers.

it doesn't come back.

Besides removing phi cycles that reduce to a single value, also remove dead2010-02-13T00:31:44ZBob Wilsonbob.wilson@apple.com2010-02-13T00:31:44Zurn:sha1:bf9b221c006a99d6f117c1048412859d5637bcde

away. This (together with my previous change for phi cycles) fixes Apple
radar 7627077.

Reapply the new LoopStrengthReduction code, with compile time and2010-02-12T10:34:29ZDan Gohmangohman@apple.com2010-02-12T10:34:29Zurn:sha1:572645cf84060c0fc25cb91d38cb9079918b3a88
bug fixes, and with improved heuristics for analyzing foreign-loop
addrecs.
This change also flattens IVUsers, eliminating the stride-oriented
groupings, which makes it easier to work with.

Add a new pass on machine instructions to optimize away PHI cycles that 2010-02-12T01:30:21ZBob Wilsonbob.wilson@apple.com2010-02-12T01:30:21Zurn:sha1:fe61fb1e1082c81653ed78efd6d471592a2e57ad
reduce down to a single value. InstCombine already does this transformation
but DAG legalization may introduce new opportunities. This has turned out to
be important for ARM where 64-bit values are split up during type legalization:
InstCombine is not able to remove the PHI cycles on the 64-bit values but
the separate 32-bit values can be optimized. I measured the compile time
impact of this (running llc on 176.gcc) and it was not significant.
