2007-12-08Fix a significant code quality regression I introduced on PPC64 quite Chris Lattner
a while ago. We now produce: _foo: mflr r0 std r0, 16(r1) ld r2, 16(r1) std r2, 0(r3) ld r0, 16(r1) mtlr r0 blr instead of: _foo: mflr r0 std r0, 16(r1) lis r0, 0 ori r0, r0, 16 ldx r2, r1, r0 std r2, 0(r3) ld r0, 16(r1) mtlr r0 blr for: void foo(void **X) { *X = __builtin_return_address(0); } on ppc64. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44701 91177308-0d34-0410-b5e6-96231b3b80d8

different places to mean different things. Document what the one in PPCFunctionInfo means and when it is valid. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44699 91177308-0d34-0410-b5e6-96231b3b80d8

2007-12-06third time around: instead of disabling this completely,Chris Lattner
only disable it if we don't know it will be obviously profitable. Still fixme, but less so. :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44658 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-06Actually, disable this code for now. More analysis and improvements toChris Lattner
the X86 backend are needed before this should be enabled by default. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44657 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-06implement a readme entry, compiling the code into:Chris Lattner
_foo: movl $12, %eax andl 4(%esp), %eax movl _array(%eax), %eax ret instead of: _foo: movl 4(%esp), %eax shrl $2, %eax andl $3, %eax movl _array(,%eax,4), %eax ret As it turns out, this triggers all the time, in a wide variety of situations, for example, I see diffs like this in various programs: - movl 8(%eax), %eax - shll $2, %eax - andl $1020, %eax - movl (%esi,%eax), %eax + movzbl 8(%eax), %eax + movl (%esi,%eax,4), %eax - shll $2, %edx - andl $1020, %edx - movl (%edi,%edx), %edx + andl $255, %edx + movl (%edi,%edx,4), %edx Unfortunately, I also see stuff like this, which can be fixed in the X86 backend: - andl $85, %ebx - addl _bit_count(,%ebx,4), %ebp + shll $2, %ebx + andl $340, %ebx + addl _bit_count(%ebx), %ebp git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44656 91177308-0d34-0410-b5e6-96231b3b80d8
