From f14beced2b3120f5f65d29e4553e478f3012345e Mon Sep 17 00:00:00 2001 From: Hal Finkel Date: Mon, 11 Nov 2013 14:58:40 +0000 Subject: Add PPC option for full register names in asm On non-Darwin PPC systems, we currently strip off the register name prefix prior to instruction printing. So instead of something like this: mr r3, r4 we print this: mr 3, 4 The first form is the default on Darwin, and is understood by binutils, but not yet understood by our integrated assembler. Once our integrated-as understands full register names as well, this temporary option will be replaced by tying this functionality to the verbose-asm option. The numeric-only form is compatible with legacy assemblers and tools, and is also gcc's default on most PPC systems. On the other hand, it is harder to read, and there are some analysis tools that expect full register names. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194384 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/CodeGen/PowerPC/reg-names.ll | 17 +++++++++++++++++ 1 file changed, 17 insertions(+) create mode 100644 test/CodeGen/PowerPC/reg-names.ll (limited to 'test/CodeGen/PowerPC/reg-names.ll') diff --git a/test/CodeGen/PowerPC/reg-names.ll b/test/CodeGen/PowerPC/reg-names.ll new file mode 100644 index 00000000000..f8fa7e4020e --- /dev/null +++ b/test/CodeGen/PowerPC/reg-names.ll @@ -0,0 +1,17 @@ +; RUN: llc -mtriple=powerpc64-unknown-linux-gnu < %s | FileCheck %s +; RUN: llc -mtriple=powerpc64-unknown-linux-gnu -ppc-asm-full-reg-names < %s | FileCheck -check-prefix=CHECK-FN %s + +define i64 @test1(i64 %a, i64 %b) { +; CHECK-LABEL: @test1 +; CHECK-FN-LABEL: @test1 + +entry: + ret i64 %b + +; CHECK: mr 3, 4 +; CHECK-FN: mr r3, r4 + +; CHECK: blr +; CHECK-FN: blr +} + -- cgit v1.2.3
