2012-08-24Fix call instruction operands in ARMFastISel.Jakob Stoklund Olesen
The ARM BL and BLX instructions don't have predicate operands, but the thumb variants tBL and tBLX do. The argument registers should be added as implicit uses. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162593 91177308-0d34-0410-b5e6-96231b3b80d8

2012-08-16[arm-fast-isel] Add support for fastcc.Jush Lu
Without fastcc support, the caller just falls through to CallingConv::C for fastcc, but callee still uses fastcc, this inconsistency of calling convention is a problem, and fastcc support can fix it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162013 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-03Fall back to selection DAG isel for calls to builtin functions.Bob Wilson
Fast isel doesn't currently have support for translating builtin function calls to target instructions. For embedded environments where the library functions are not available, this is a matter of correctness and not just optimization. Most of this patch is just arranging to make the TargetLibraryInfo available in fast isel. <rdar://problem/12008746> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161232 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-11Re-enable the CMN instruction.Bill Wendling
We turned off the CMN instruction because it had semantics which we weren't getting correct.

2012-04-06Deduplicate ARM call-related instructions.Jakob Stoklund Olesen
We had special instructions for iOS because r9 is call-clobbered, but that is represented dynamically by the register mask operands now, so there is no need for the pseudo-instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@154144 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-16Check if we can handle the arguments of a call (and therefore the call) inBill Wendling
fast-isel before emitting code. If the program bails after code was emitted, then it could lead to the stack being adjusted more than once (two CALLSEQ_BEGINs emitted) but being adjuste back only once after the call. This leads to general badness and gnashing of teeth. <rdar://problem/11050630> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@152959 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-07[fast-isel] ARMEmitCmp generates FMSTAT, which transfers the floating-point Chad Rosier
condition flags to CPSR. This allows us to simplify SelectCmp. Patch by Zonr Chang <zonr.xchg@gmail.com>. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@152243 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-06Split fpscr into two registers: FPSCR and FPSCR_NZCV.Lang Hames
The fpscr register contains both flags (set by FP operations/comparisons) and control bits. The control bits (FPSCR) should be reserved, since they're always available and needn't be defined before use. The flag bits (FPSCR_NZCV) should like to be unreserved so they can be hoisted by MachineCSE. This fixes PR12165. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@152076 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-24Switch ARM target to register masks.Jakob Stoklund Olesen
I'll let the buildbots determine the compile time improvements from this change, but 464.h264ref has 5% faster codegen at -O2. This patch does cause some assembly changes. Branch folding can make different decisions about calls with dead return values. CriticalAntiDepBreaker may choose different registers because its liveness tracking is affected. MachineCopyPropagation may sometimes leave a dead copy behind. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151331 91177308-0d34-0410-b5e6-96231b3b80d8
