Allow gv + offset when using rip addressing mode. Before: _main: subq $8, %rsp leaq _X(%rip), %rax movsd 8(%rax), %xmm1 movss _X(%rip), %xmm0 call _t xorl %ecx, %ecx movl %ecx, %eax addq $8, %rsp ret Now: _main: subq $8, %rsp movsd _X+8(%rip), %xmm1 movss _X(%rip), %xmm0 call _t xorl %ecx, %ecx movl %ecx, %eax addq $8, %rsp ret Notice there is another idiotic codegen issue that needs to be fixed asap: xorl %ecx, %ecx movl %ecx, %eax git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46850 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/CodeGen/X86/x86-64-gv-offset.ll | 14 ++++++++++++++ 1 file changed, 14 insertions(+) create mode 100644 test/CodeGen/X86/x86-64-gv-offset.ll (limited to 'test/CodeGen/X86/x86-64-gv-offset.ll') diff --git a/test/CodeGen/X86/x86-64-gv-offset.ll b/test/CodeGen/X86/x86-64-gv-offset.ll new file mode 100644 index 0000000..b89e1b9 --- /dev/null +++ b/test/CodeGen/X86/x86-64-gv-offset.ll @@ -0,0 +1,14 @@ +; RUN: llvm-as < %s | llc -mtriple=x86_64-apple-darwin | not grep lea + + %struct.x = type { float, double } +@X = global %struct.x { float 1.000000e+00, double 2.000000e+00 }, align 16 ; <%struct.x*> [#uses=2] + +define i32 @main() nounwind { +entry: + %tmp2 = load float* getelementptr (%struct.x* @X, i32 0, i32 0), align 16 ; [#uses=1] + %tmp4 = load double* getelementptr (%struct.x* @X, i32 0, i32 1), align 8 ; [#uses=1] + tail call void @t( float %tmp2, double %tmp4 ) nounwind + ret i32 0 +} + +declare void @t(float, double) -- cgit v1.1
