From 51cc3c13eac78da242f0518fc42580e48dd5304f Mon Sep 17 00:00:00 2001 From: Nicolas Geoffray Date: Wed, 16 Apr 2008 20:46:05 +0000 Subject: Correlate stubs with functions in JIT: when emitting a stub, the JIT tells the memory manager which function the stub will resolve. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49814 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Target/PowerPC/PPCJITInfo.cpp | 12 +++++++----- 1 file changed, 7 insertions(+), 5 deletions(-) (limited to 'lib/Target/PowerPC/PPCJITInfo.cpp') diff --git a/lib/Target/PowerPC/PPCJITInfo.cpp b/lib/Target/PowerPC/PPCJITInfo.cpp index 6dea3d3306..461cfec34a 100644 --- a/lib/Target/PowerPC/PPCJITInfo.cpp +++ b/lib/Target/PowerPC/PPCJITInfo.cpp @@ -15,6 +15,7 @@ #include "PPCJITInfo.h" #include "PPCRelocations.h" #include "PPCTargetMachine.h" +#include "llvm/Function.h" #include "llvm/CodeGen/MachineCodeEmitter.h" #include "llvm/Config/alloca.h" #include "llvm/Support/Debug.h" @@ -338,12 +339,13 @@ defined(__APPLE__) #endif } -void *PPCJITInfo::emitFunctionStub(void *Fn, MachineCodeEmitter &MCE) { +void *PPCJITInfo::emitFunctionStub(const Function* F, void *Fn, + MachineCodeEmitter &MCE) { // If this is just a call to an external function, emit a branch instead of a // call.
