From bc52cada0933f353d30da7b49af9a641bdb2c57d Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Wed, 25 Jun 2008 17:18:44 +0000 Subject: Switch the PPC backend and target-independent JIT to use the libsystem InvalidateInstructionCache method instead of calling through a hook on the JIT. This is a host feature, not a target feature. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52734 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Target/PowerPC/PPCJITInfo.cpp | 29 +++-------------------------- 1 file changed, 3 insertions(+), 26 deletions(-) (limited to 'lib/Target/PowerPC/PPCJITInfo.cpp') diff --git a/lib/Target/PowerPC/PPCJITInfo.cpp b/lib/Target/PowerPC/PPCJITInfo.cpp index f400297..41c755b 100644 --- a/lib/Target/PowerPC/PPCJITInfo.cpp +++ b/lib/Target/PowerPC/PPCJITInfo.cpp @@ -17,7 +17,7 @@ #include "PPCTargetMachine.h" #include "llvm/Function.h" #include "llvm/CodeGen/MachineCodeEmitter.h" -#include "llvm/Config/alloca.h" +#include "llvm/System/Memory.h" #include "llvm/Support/Debug.h" #include using namespace llvm; @@ -330,29 +330,6 @@ defined(__APPLE__) extern "C" void sys_icache_invalidate(const void *Addr, size_t len); #endif -void PPCJITInfo::InvalidateInstructionCache(const void *Addr, unsigned len) { -#if (defined(__POWERPC__) || defined (__ppc__) || \ - defined(_POWER) || defined(_ARCH_PPC)) -# if defined(__APPLE__) - sys_icache_invalidate(Addr, len); -# elif defined(__GNUC__) - const size_t LineSize = 32; - - const intptr_t Mask = ~(LineSize - 1); - const intptr_t StartLine = ((intptr_t) Addr) & Mask; - const intptr_t EndLine = ((intptr_t) Addr + len + LineSize - 1) & Mask; - - for (intptr_t Line = StartLine; Line < EndLine; Line += LineSize) - asm volatile("dcbf 0, %0" : : "r"(Line)); - asm volatile("sync"); - - for (intptr_t Line = StartLine; Line < EndLine; Line += LineSize) - asm volatile("icbi 0, %0" : : "r"(Line)); - asm volatile("isync"); -# endif -#endif -} - 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 @@ -369,7 +346,7 @@ void *PPCJITInfo::emitFunctionStub(const Function* F, void *Fn, MCE.emitWordBE(0); MCE.emitWordBE(0); EmitBranchToAt(Addr, (intptr_t)Fn, false, is64Bit); - InvalidateInstructionCache((void*)Addr, 7*4); + sys::Memory::InvalidateInstructionCache((void*)Addr, 7*4); return MCE.finishFunctionStub(F); } @@ -397,7 +374,7 @@ void *PPCJITInfo::emitFunctionStub(const Function* F, void *Fn, MCE.emitWordBE(0); MCE.emitWordBE(0); EmitBranchToAt(BranchAddr, (intptr_t)Fn, true, is64Bit); - InvalidateInstructionCache((void*)Addr, 10*4); + sys::Memory::InvalidateInstructionCache((void*)Addr, 10*4); return MCE.finishFunctionStub(F); } -- cgit v1.1
