Author: José Fonseca <[email protected]> Date: Sun Jun 13 13:13:11 2010 +0100 gallivm: Override some of the default target options. In particular: - enable LLVM <-> GDB integration for JIT code - disable frame-pointer elimination on debug/profile builds - enable fast-math. --- src/gallium/auxiliary/gallivm/lp_bld_init.c | 5 ++++ src/gallium/auxiliary/gallivm/lp_bld_misc.cpp | 26 +++++++++++++++++++++++++ 2 files changed, 31 insertions(+), 0 deletions(-) diff --git a/src/gallium/auxiliary/gallivm/lp_bld_init.c b/src/gallium/auxiliary/gallivm/lp_bld_init.c index 0a690ea..44cfdc4 100644 --- a/src/gallium/auxiliary/gallivm/lp_bld_init.c +++ b/src/gallium/auxiliary/gallivm/lp_bld_init.c @@ -78,6 +78,9 @@ enum LLVM_CodeGenOpt_Level { extern void lp_register_oprofile_jit_event_listener(LLVMExecutionEngineRef EE); +extern void +lp_set_target_options(void); + void lp_build_init(void) @@ -86,6 +89,8 @@ lp_build_init(void) gallivm_debug = debug_get_flags_option("GALLIVM_DEBUG", lp_bld_debug_flags, 0 ); #endif + lp_set_target_options(); + LLVMInitializeNativeTarget(); LLVMLinkInJIT(); diff --git a/src/gallium/auxiliary/gallivm/lp_bld_misc.cpp b/src/gallium/auxiliary/gallivm/lp_bld_misc.cpp index f004c0a..87e9f00 100644 --- a/src/gallium/auxiliary/gallivm/lp_bld_misc.cpp +++ b/src/gallium/auxiliary/gallivm/lp_bld_misc.cpp @@ -36,6 +36,7 @@ #include <llvm-c/Core.h> #include <llvm-c/ExecutionEngine.h> +#include <llvm/Target/TargetOptions.h> #include <llvm/ExecutionEngine/ExecutionEngine.h> #include <llvm/ExecutionEngine/JITEventListener.h> @@ -119,3 +120,28 @@ lp_register_oprofile_jit_event_listener(LLVMExecutionEngineRef EE) { llvm::unwrap(EE)->RegisterJITEventListener(llvm::createOProfileJITEventListener()); } + + +extern "C" void +lp_set_target_options(void) +{ +#if defined(DEBUG) +#if HAVE_LLVM >= 0x0207 + llvm::JITEmitDebugInfo = true; +#endif +#endif + +#if defined(DEBUG) || defined(PROFILE) + llvm::NoFramePointerElim = true; +#if HAVE_LLVM >= 0x0207 + llvm::NoFramePointerElimNonLeaf = true; +#endif +#endif + + llvm::NoExcessFPPrecision = false; + + /* XXX: Investigate this */ +#if 0 + llvm::UnsafeFPMath = true; +#endif +} _______________________________________________ mesa-commit mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/mesa-commit
