From 57a2306074989dfd6e1c0d9ddd2b5084f664e2a9 Mon Sep 17 00:00:00 2001 From: Evan Cheng Date: Sat, 20 Jan 2007 02:07:13 +0000 Subject: [PATCH] We not align the final stack slot but instead let the target do so in emitPrologue(). Each target can make adjustments to the stack frame and re-align the stack as it deem appropriate. Do not align it twice which can end up wasting stack space. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33387 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/PrologEpilogInserter.cpp | 7 ------- 1 file changed, 7 deletions(-) diff --git a/lib/CodeGen/PrologEpilogInserter.cpp b/lib/CodeGen/PrologEpilogInserter.cpp index 51555fa69eb..d056da96491 100644 --- a/lib/CodeGen/PrologEpilogInserter.cpp +++ b/lib/CodeGen/PrologEpilogInserter.cpp @@ -387,13 +387,6 @@ void PEI::calculateFrameObjectOffsets(MachineFunction &Fn) { } } - - // Align the final stack pointer offset, but only if there are calls in the - // function.
