Eric Christopher a8aaaee379 Rewrite the darwin tlv support to use a chain and return to copying 
the output to the correct register. Fixes a hidden problem uncovered
by the last patch where we'd try to DAG combine our MVT::Other node
oddly.

referencing the stack pointer as they say they are.

Jim Grosbach bd30afe4c2 When using multiple instructions to reference a frame index, make sure to 
update the opcode when necessary as well as the source register.

Jim Grosbach 0b2630c500 The add/sub SP instructions are really pseudos. The assembler should ignore 
them.

Bill Wendling c4d333f02a Attempt to make the bit-twiddling readable resulted in the binary value being 
overwritten.

Bill Wendling 3392bfc8f3 The BLX instruction is encoded differently than the BL, because why not? In 
particular, the immediate has 20-bits of value instead of 21. And bit 0 is '0'
always. Going through the BL fixup encoding was trashing the "bit 0 is '0'"
invariant.

Attempt to get the encoding at slightly more correct with this.

Eric Christopher d84970ae8b Remove extraneous copy from DAG conversion for darwin tls. This was 
popping up at O0 when it wasn't folded and the fast allocator would
complain.

Jason W Kim c79c5f6e8c ARM/MC/ELF TPsoft is now a proper pseudo inst. 
Added test to check bl __aeabi_read_tp gets emitted properly for ELF/ASM
as well as ELF/OBJ (including fixup)

Also added support for ELF::R_ARM_TLS_IE32

llvm-svn: 121297
 2010-12-08 22:29:28 +00:00
Jim Grosbach 572e56dfb2 Simplify T2 operand assignment notation a bit. No need to specify a bit range 
for the source field when it's the whole thing that's being referenced.

llvm-svn: 121291
 2010-12-08 22:10:43 +00:00

Andrew Trick 00067fb147 Generalize PostRAHazardRecognizer so it can be used in any pass for 
both forward and backward scheduling. Rename it to
ScoreboardHazardRecognizer (Scoreboard is one word). Remove integer
division from the scoreboard's critical path.

llvm-svn: 121216
 2010-12-08 00:21:33 +00:00
Owen Anderson 0f7142d808 VLDR fixups need special handling under Thumb. While the encoding is the same, 
the order of the bytes in the data stream is flipped around.

Evan Cheng 775ead3293 Fix a bad prologue / epilogue codegen bug where the compiler would emit illegal 
vpush instructions to save / restore VFP / NEON registers like this:
vpush {d8,d10,d11}
vpop {d8,d10,d11}

vpush and vpop do not allow gaps in the register list.
