Author: sbruno Date: Wed Sep 3 14:16:50 2014 New Revision: 271025 URL: http://svnweb.freebsd.org/changeset/base/271025 Log: MFV: Only emit movw on ARMv6T2 Building for the FreeBSD default target ARMv6 was emitting movw ASM on certain test cases (found building qmake4/5 for ARM). Don't do that, moreover, the AS in base doesn't understand this instruction for this target. One would need to use --integrated-as to get this to build if desired. http://llvm.org/viewvc/llvm-project?view=revision&revision=216989 Submitted by: ian Reviewed by: dim Obtained from: llvm.org MFC after: 2 days Modified: head/contrib/llvm/lib/Target/ARM/ARMInstrInfo.td Modified: head/contrib/llvm/lib/Target/ARM/ARMInstrInfo.td ============================================================================== --- head/contrib/llvm/lib/Target/ARM/ARMInstrInfo.td Wed Sep 3 14:06:12 2014 (r271024) +++ head/contrib/llvm/lib/Target/ARM/ARMInstrInfo.td Wed Sep 3 14:16:50 2014 (r271025) @@ -3248,7 +3248,8 @@ def : ARMPat<(ARMaddc GPR:$src, imm0_655 def : ARMPat<(ARMadde GPR:$src, so_imm_not:$imm, CPSR), (SBCri GPR:$src, so_imm_not:$imm)>; def : ARMPat<(ARMadde GPR:$src, imm0_65535_neg:$imm, CPSR), - (SBCrr GPR:$src, (MOVi16 (imm_not_XFORM imm:$imm)))>; + (SBCrr GPR:$src, (MOVi16 (imm_not_XFORM imm:$imm)))>, + Requires<[IsARM, HasV6T2]>; // Note: These are implemented in C++ code, because they have to generate // ADD/SUBrs instructions, which use a complex pattern that a xform function
