From b164d67d07d847346bf6364179dd642bc48592d8 Mon Sep 17 00:00:00 2001 From: Benjamin Kramer Date: Fri, 22 Feb 2013 20:55:17 +0000 Subject: Driver: Pass down the -march setting down to -cc1as on x86 too. The assembler historically didn't make use of any target features, but this has changed when support for old CPUs that don't support long nops was added. llvm-svn: 175919 --- clang/lib/Driver/Tools.cpp | 14 ++++++++++++++ 1 file changed, 14 insertions(+) (limited to 'clang/lib/Driver/Tools.cpp') diff --git a/clang/lib/Driver/Tools.cpp b/clang/lib/Driver/Tools.cpp index 445ae5358be..12833a84229 100644 --- a/clang/lib/Driver/Tools.cpp +++ b/clang/lib/Driver/Tools.cpp @@ -3325,6 +3325,15 @@ void ClangAs::AddARMTargetArgs(const ArgList &Args, addFPMathArgs(D, A, Args, CmdArgs, getARMTargetCPU(Args, Triple)); } +void ClangAs::AddX86TargetArgs(const ArgList &Args, + ArgStringList &CmdArgs) const { + // Set the CPU based on -march=. + if (const char *CPUName = getX86TargetCPU(Args, getToolChain().getTriple())) { + CmdArgs.push_back("-target-cpu"); + CmdArgs.push_back(CPUName); + } +} + /// Add options related to the Objective-C runtime/ABI. /// /// Returns true if the runtime is non-fragile. @@ -3500,6 +3509,11 @@ void ClangAs::ConstructJob(Compilation &C, const JobAction &JA, case llvm::Triple::thumb: AddARMTargetArgs(Args, CmdArgs); break; + + case llvm::Triple::x86: + case llvm::Triple::x86_64: + AddX86TargetArgs(Args, CmdArgs); + break; } // Ignore explicit -force_cpusubtype_ALL option. -- cgit v1.2.3
