2010-07-30Many Thumb2 instructions can reference the full ARM register set (i.e.,Jim Grosbach
have 4 bits per register in the operand encoding), but have undefined behavior when the operand value is 13 or 15 (SP and PC, respectively). The trivial coalescer in linear scan sometimes will merge a copy from SP into a subsequent instruction which uses the copy, and if that instruction cannot legally reference SP, we get bad code such as: mls r0,r9,r0,sp instead of: mov r2, sp mls r0, r9, r0, r2 This patch adds a new register class for use by Thumb2 that excludes the problematic registers (SP and PC) and is used instead of GPR for those operands which cannot legally reference PC or SP. The trivial coalescer explicitly requires that the register class of the destination for the COPY instruction contain the source register for the COPY to be considered for coalescing. This prevents errant instructions like that above. PR7499 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@109842 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-29Revert r109652, and remove the offending assert in loadRegFromStackSlot instead.Jakob Stoklund Olesen
We do sometimes load from a too small stack slot when dealing with x86 arguments (varargs and smaller-than-32-bit args). It looks like we know what we are doing in those cases, so I am going to remove the assert instead of artifically enlarging stack slot sizes. The assert in storeRegToStackSlot stays in. We don't want to write beyond the bounds of a stack slot. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@109764 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-29CrashRecoveryContext: Add a simple POSIX implementation.Daniel Dunbar
- This works, but won't handle crashes on stack overflow, or signals delivered to a thread other than the one that crashed. The latter is particular annoying on Darwin, because SIGABRT tends to go to the main thread. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@109717 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-29Fix a bug in the -regalloc=fast handling of exotic two-address instruction withJakob Stoklund Olesen
multiple defs, like t2LDRSB_POST. The first def could accidentally steal the physreg that the second, tied def was required to be allocated to. Now, the tied use-def is treated more like an early clobber, and the physreg is reserved before allocating the other defs. This would never be a problem when the tied def was the only def which is the usual case. This fixes MallocBench/gs for thumb2 -O0. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@109715 91177308-0d34-0410-b5e6-96231b3b80d8
