From 8f4ee56e49911ca12ad2c006bf7f94c85ceeb404 Mon Sep 17 00:00:00 2001 From: Tom Stellard Date: Tue, 23 Sep 2014 16:15:52 -0400 Subject: gallivm: Disable gallivm to fix build with LLVM 3.6 LLVM commit r218316 removes the JITMemoryManager class, which is the parent for a seemingly important class in gallivm. In order to fix the build, I've wrapped most of lp_bld_misc.cpp in if HAVE_LLVM < 0x0306 and modifyed the lp_build_create_jit_compiler_for_module() function to return false for 3.6 and newer which effectively disables the gallivm functionality. I realize this is overkill, but I could not come up with a simple solution to fix the build. Also, since 3.6 will be the first release without the old JIT, it would be really great if we could move gallivm to use the C API only for accessing MCJIT. There is still time before the 3.6 release to extend the C API in case it is missing some functionality that is required by gallivm. --- src/gallium/auxiliary/gallivm/lp_bld_misc.cpp | 10 ++++++++++ 1 file changed, 10 insertions(+) (limited to 'src') diff --git a/src/gallium/auxiliary/gallivm/lp_bld_misc.cpp b/src/gallium/auxiliary/gallivm/lp_bld_misc.cpp index 2fd85a82090..1c42e8fdd5e 100644 --- a/src/gallium/auxiliary/gallivm/lp_bld_misc.cpp +++ b/src/gallium/auxiliary/gallivm/lp_bld_misc.cpp @@ -143,6 +143,7 @@ lp_set_store_alignment(LLVMValueRef Inst, llvm::unwrap(Inst)->setAlignment(Align); } +#if HAVE_LLVM < 0x0306 /* * Delegating is tedious but the default manager class is hidden in an @@ -398,6 +399,7 @@ class ShaderMemoryManager : public DelegatingJITMemoryManager { llvm::JITMemoryManager *ShaderMemoryManager::TheMM = 0; unsigned ShaderMemoryManager::NumUsers = 0; +#endif /** * Same as LLVMCreateJITCompilerForModule, but: @@ -420,6 +422,11 @@ lp_build_create_jit_compiler_for_module(LLVMExecutionEngineRef *OutJIT, { using namespace llvm; +#if HAVE_LLVM >= 0x0306 + *OutError = strdup("MCJIT not supported"); + return 1; +#else + std::string Error; #if HAVE_LLVM >= 0x0306 EngineBuilder builder(std::unique_ptr(unwrap(M))); @@ -528,6 +535,7 @@ lp_build_create_jit_compiler_for_module(LLVMExecutionEngineRef *OutJIT, delete MM; *OutError = strdup(Error.c_str()); return 1; +#endif } @@ -535,5 +543,7 @@ extern "C" void lp_free_generated_code(struct lp_generated_code *code) { +#if HAVE_LLVM < 0x0306 ShaderMemoryManager::freeGeneratedCode(code); +#endif } -- cgit v1.2.3
