Jeffrey Yasskin	0c46d96fd0	Partially revert r91626. Materializing extra functions to determine whether ... they're available_externally broke VMKit, which was relying on the fact that functions would only be materialized when they were first called. We'll have to wait for http://llvm.org/PR5737 to really fix this. I also added a test for one of the F->isDeclaration() calls which wasn't covered by anything else in the test suite. llvm-svn: 91943	2009-12-22 23:47:23 +00:00
Jeffrey Yasskin	d06c7e46a2	Reinstate r91208 to fix available_externally linkage for globals, with ... nlewycky's fix to add -rdynamic so the JIT can look symbols up in Linux builds of the JITTests binary. llvm-svn: 91250	2009-12-13 20:30:32 +00:00
Jeffrey Yasskin	8ff8b897a5	Fix http://llvm.org/PR4822: allow module deletion after a function has been ... compiled. When functions are compiled, they accumulate references in the JITResolver's stub maps. This patch removes those references when the functions are destroyed. It's illegal to destroy a Function when any thread may still try to call its machine code. This patch also updates r83987 to use ValueMap instead of explicit CallbackVHs and fixes a couple "do stuff inside assert()" bugs from r84522. llvm-svn: 84975	2009-10-23 22:37:43 +00:00
Jeffrey Yasskin	c431f61520	Add a JITEventListener interface that gets called back when a new function is ... emitted or the machine code for a function is freed. Chris mentioned that we may also want a notification when a stub is emitted, but that'll be a future change. I intend to use this to tell oprofile where functions are emitted and what lines correspond to what addresses. llvm-svn: 74157	2009-06-25 02:04:04 +00:00
