From 8ae32357b32fef5c1484fb85473bc3ad809f0b2e Mon Sep 17 00:00:00 2001 From: Nicolas Geoffray Date: Sun, 20 Apr 2008 08:33:02 +0000 Subject: Do not hold the JIT lock when materializing a function and verify if the function has already been codegen'd. This is required by the Java class loading mechanism which executes Java code when materializing a function. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49988 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/ExecutionEngine/JIT/JIT.cpp | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) diff --git a/lib/ExecutionEngine/JIT/JIT.cpp b/lib/ExecutionEngine/JIT/JIT.cpp index 281869a..9e89e3c 100644 --- a/lib/ExecutionEngine/JIT/JIT.cpp +++ b/lib/ExecutionEngine/JIT/JIT.cpp @@ -301,7 +301,6 @@ void JIT::runJITOnFunction(Function *F) { /// specified function, compiling it if neccesary. /// void *JIT::getPointerToFunction(Function *F) { - MutexGuard locked(lock); if (void *Addr = getPointerToGlobalIfAvailable(F)) return Addr; // Check if function already code gen'd @@ -326,7 +325,13 @@ void *JIT::getPointerToFunction(Function *F) { abort(); } } + + if (void *Addr = getPointerToGlobalIfAvailable(F)) { + return Addr; + } + MutexGuard locked(lock); + if (F->isDeclaration()) { void *Addr = getPointerToNamedFunction(F->getName()); addGlobalMapping(F, Addr); -- cgit v1.1
