Evan Cheng	4e4eb0b00c	Restore AsmWriterEmitter.cpp back to 74742. The recent changes broke Thumb. ... llvm-svn: 76398	2009-07-20 06:10:07 +00:00
Evan Cheng	0794c6a083	Smarter isel of ldrsb / ldrsh. Only make use of these when [r,r] address is feasible. ... llvm-svn: 75360	2009-07-11 07:08:13 +00:00
Evan Cheng	cd4cdd1157	Major changes to Thumb (not Thumb2). Many 16-bit instructions either modifies CPSR when they are outside the IT blocks, or they can predicated when in Thumb2. Move the implicit def of CPSR to an optional def which defaults CPSR. This allows the 's' bit to be toggled dynamically. ... A side-effect of this change is asm printer is now using unified assembly. There are some minor clean ups and fixes as well. llvm-svn: 75359	2009-07-11 06:43:01 +00:00
