* During PEI, if the immediate value of sp + offset is too large (i.e. somethingEvan Cheng2007-01-301-21/+102

* - Fix codegen for pc relative constant (e.g. JT) in thumb mode:Evan Cheng2007-01-307-47/+96
| | | | | | | | | | | | | | | | | | | .set PCRELV0, (LJTI1_0_0-(LPCRELL0+4)) LPCRELL0: add r1, pc, #PCRELV0 This is not legal since add r1, pc, #c requires the constant be a multiple of 4. Do the following instead: .set PCRELV0, (LJTI1_0_0-(LPCRELL0+4)) LPCRELL0: mov r1, #PCRELV0 add r1, pc - In thumb mode, it's not possible to use .set generate a pc relative stub address. The stub is ARM code which is in a different section from the thumb code. Load the value from a constpool instead. - Some asm printing clean up. llvm-svn: 33664

LR is not used as a GPR in thumb mode so it can be clobbered if it is properly spilled / restored in prologue / epilogue. - If LR is force spilled but no far jump has been emitted, try undo'ing the spill by: push lr -> delete pop pc -> bx lr llvm-svn: 33650

* Propagate changes from my local tree. This patch includes:Anton Korobeynikov2007-01-287-775/+383
| | | | | | | | | | | | | | | | | | | | | | 1. New parameter attribute called 'inreg'. It has meaning "place this parameter in registers, if possible". This is some generalization of gcc's regparm(n) attribute. It's currently used only in X86-32 backend. 2. Completely rewritten CC handling/lowering code inside X86 backend. Merged stdcall + c CCs and fastcall + fast CC. 3. Dropped CSRET CC. We cannot add struct return variant for each target-specific CC (e.g. stdcall + csretcc and so on). 4. Instead of CSRET CC introduced 'sret' parameter attribute. Setting in on first attribute has meaning 'This is hidden pointer to structure return. Handle it gently'. 5. Fixed small bug in llvm-extract + add new feature to FunctionExtraction pass, which relinks all internal-linkaged callees from deleted function to external linkage. This will allow further linking everything together. NOTEs: 1. Documentation will be updated soon. 2. llvm-upgrade should be improved to translate csret => sret. Before this, there will be some unexpected test fails. llvm-svn: 33597
