* Refactor away tSpill and tRestore pseudos in ARM backend.Jim Grosbach2011-06-291-1/+1
| | | | | | | The tSpill and tRestore instructions are just copies of the tSTRspi and tLDRspi instructions, respectively. Just use those directly instead. llvm-svn: 134092
* Fix coordination for using R4 in Thumb1 as a scratch for SP restore.Jim Grosbach2011-06-131-2/+2
| | | | | | | | The logic for reserving R4 for use as a scratch needs to match that for actually using it. Also, it's not necessary for immediate <=508, so adjust the value checked. llvm-svn: 132934
* Implement frame unwinding information emission for Thumb1. Not finished yet ↵Anton Korobeynikov2011-03-051-11/+17
| | | | | | because there is no way given the constpool index to examine the actual entry: the reason is clones inserted by constant island pass, which are not tracked at all! The only connection is done during asmprinting time via magic label names which is really gross and needs to be eventually fixed. llvm-svn: 127104
* Preliminary support for ARM frame save directives emission via MI flags.Anton Korobeynikov2011-03-051-4/+4
| | | | | | | This is just very first approximation how the stuff should be done (e.g. ARM-only for now). More to follow. llvm-svn: 127101
* Teach frame lowering to ignore debug values after the terminators.Jakob Stoklund Olesen2011-01-131-1/+1
| | | | llvm-svn: 123399
* Even if we don't have 7 bytes of stack space we may need to save andEric Christopher2011-01-111-1/+8
| | | | | | | | restore the stack pointer from the frame pointer on thumbv6. Fixes rdar://8819685 llvm-svn: 123196
* Rename TargetFrameInfo into TargetFrameLowering. Also, put couple of FIXMEs ↵Anton Korobeynikov2011-01-101-0/+345
and fixes here and there. llvm-svn: 123170
