* Make the need-stub variables accurate and consistent. In the case ofJeffrey Yasskin2009-11-071-15/+13
| | | | | | | | | | | | | | MachineRelocations, "stub" always refers to a far-call stub or a load-a-faraway-global stub, so this patch adds "Far" to the term. (Other stubs are used for lazy compilation and dlsym address replacement.) The variable was also inconsistent between the positive and negative sense, and the positive sense ("NeedStub") was more demanding than is accurate (since a nearby-enough function can be called directly even if the platform often requires a stub). Since the negative sense causes double-negatives, I switched to "MayNeedFarStub" globally. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@86363 91177308-0d34-0410-b5e6-96231b3b80d8

This patch also removes the Function* parameter to JITEventListener::NotifyFreeingMachineCode() since it can cause that to be called when the Function is partially destroyed.

It's illegal to destroy a Function when any thread may still try to call its machine code.

* Move the Function*->allocated blocks map from the JITMemoryManager to theJeffrey Yasskin2009-10-202-34/+30
| | | | | | | | | | | | | | | | | JITEmitter. I'm gradually making Functions auto-remove themselves from the JIT when they're destroyed. In this case, the Function needs to be removed from the JITEmitter, but the map recording which Functions need to be removed lived behind the JITMemoryManager interface, which made things difficult. This patch replaces the deallocateMemForFunction(Function*) method with a pair of methods deallocateFunctionBody(void *) and deallocateExceptionTable(void *) corresponding to the two startFoo/endFoo pairs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84651 91177308-0d34-0410-b5e6-96231b3b80d8
* Clean up the JITResolver stub/callsite<->function maps.Jeffrey Yasskin2009-10-191-44/+100
| | | | | | | | | | | | | | | | | | The JITResolver maps Functions to their canonical stubs and all callsites for lazily-compiled functions to their target Functions. To make Function destruction work, I'm going to need to remove all callsites on destruction, so this patch also adds the reverse mapping for that. There was an incorrect assumption in here that the only stub for a function would be the one caused by needing to lazily compile it, while x86-64 far calls and dlsym-stubs could also cause such stubs, but I didn't look for a test case that the assumption broke. This also adds DenseMapInfo<AssertingVH> so I can use DenseMaps instead of std::maps. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84522 91177308-0d34-0410-b5e6-96231b3b80d8

* Implement the JIT side of the GDB JIT debugging interface. To enable thisReid Kleckner2009-09-207-17/+374
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | feature, either build the JIT in debug mode to enable it by default or pass -jit-emit-debug to lli. Right now, the only debug information that this communicates to GDB is call frame information, since it's already being generated to support exceptions in the JIT. Eventually, when DWARF generation isn't tied so tightly to AsmPrinter, it will be easy to push that information to GDB through this interface. Here's a step-by-step breakdown of how the feature works: - The JIT generates the machine code and DWARF call frame info (.eh_frame/.debug_frame) for a function into memory. - The JIT copies that info into an in-memory ELF file with a symbol for the function. - The JIT creates a code entry pointing to the ELF buffer and adds it to a linked list hanging off of a global descriptor at a special symbol that GDB knows about. - The JIT calls a function marked noinline that GDB knows about and has put an internal breakpoint in. - GDB catches the breakpoint and reads the global descriptor to look for new code. - When sees there is new code, it reads the ELF from the inferior's memory and adds it to itself as an object file. - The JIT continues, and the next time we stop the program, we are able to produce a proper backtrace. Consider running the following program through the JIT: #include <stdio.h> void baz(short z) { long w = z + 1; printf("%d, %x\n", w, *((int*)NULL)); // SEGFAULT here } void bar(short y) { int z = y + 1; baz(z); } void foo(char x) { short y = x + 1; bar(y); } int main(int argc, char** argv) { char x = 1; foo(x); } Here is a backtrace before this patch: Program received signal SIGSEGV, Segmentation fault.
