2009-10-01Remove neonfp attribute and instead set default based on CPU string. Add ↵David Goodwin
-arm-use-neon-fp to override the default. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@83218 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-01Restore the -post-RA-scheduler flag as an override for the target ↵David Goodwin
specification. Remove -mattr for setting PostRAScheduler enable and instead use CPU string. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@83215 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-30Remove -post-RA-schedule flag and add a TargetSubtarget method to enable ↵David Goodwin
post-register-allocation scheduling. By default it is off. For ARM, enable/disable with -mattr=+/-postrasched. Enable by default for cortex-a8. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@83122 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-03Reference to hidden symbols do not have to go through non-lazy pointer in ↵Evan Cheng
non-pic mode. rdar://7187172. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80904 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-28Let Darwin linker auto-synthesize stubs and lazy-pointers. This deletes a ↵Evan Cheng
bunch of nasty code in ARM asm printer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80404 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-04Initial support for single-precision FP using NEON. Added "neonfp" attribute ↵David Goodwin
to enable. Added patterns for some binary FP operations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78081 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-02Normalize Subtarget constructors to take a target triple string instead ofDaniel Dunbar
Module*. Also, dropped uses of TargetMachine where unnecessary. The only target which still takes a TargetMachine& is Mips, I would appreciate it if someone would normalize this to match other targets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77918 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-01Fix Thumb2 function call isel. Thumb1 and Thumb2 should share the sameEvan Cheng
instructions for calls since BL and BLX are always 32-bit long and BX is always 16-bit long. Also, we should be using BLX to call external function stubs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77756 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-22Use thumb2 for ARM architectures V6T2 and later. Fix a bug in checkingBob Wilson
for "thumb" and add a check for V6T2. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73905 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-22For Darwin on ARMv6 and newer, make register r9 available for use as aBob Wilson
caller-saved register. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73901 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-08The attached patches implement most of the ARM AAPCS-VFP hard floatAnton Korobeynikov
ABI. The missing piece is support for putting "homogeneous aggregates" into registers. Patch by Sandeep Patel! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73095 91177308-0d34-0410-b5e6-96231b3b80d8
