From 491343d2fa2eff3cab331454c107a3344def2b74 Mon Sep 17 00:00:00 2001 From: Eric Christopher Date: Thu, 7 Dec 2017 22:26:19 +0000 Subject: Temporarily revert "[PowerPC] Allow tail calls of fastcc functions from C CallingConv functions." It is causing sanitizer failures on llvm tests in a bootstrapped compiler. No bot link since it's currently down, but following up to get the bot up. This reverts commit r319218. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@320106 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/CodeGen/PowerPC/duplicate-returns-for-tailcall.ll | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'test/CodeGen/PowerPC') diff --git a/test/CodeGen/PowerPC/duplicate-returns-for-tailcall.ll b/test/CodeGen/PowerPC/duplicate-returns-for-tailcall.ll index 9c0e77dafde..520efd8106f 100644 --- a/test/CodeGen/PowerPC/duplicate-returns-for-tailcall.ll +++ b/test/CodeGen/PowerPC/duplicate-returns-for-tailcall.ll @@ -42,10 +42,10 @@ if.end4: ; preds = %if.end if.then6: ; preds = %if.end4 %call7 = tail call fastcc signext i32 @call3(i32 signext %a, i32 signext %b, i32 signext %c) br label %return -; tail calling a fastcc function from a ccc function is supported. +; No duplication here because the calling convention mismatch means we won't tail-call ; CHECK_LABEL: if.then13: -; CHECK: %[[T2:[a-zA-Z0-9]+]] = tail call fastcc signext i32 @call3 -; CHECK-NEXT: ret i32 %[[T2]] +; CHECK: tail call fastcc signext i32 @call3 +; CHECK-NEXT: br return: ; preds = %if.end4, %if.then6, %if.then2, %if.then %retval.0 = phi i32 [ %call, %if.then ], [ %call3, %if.then2 ], [ %call7, %if.then6 ], [ %c, %if.end4 ] -- cgit v1.2.3
