* Add target analysis passes to the codegen pipeline for MCJIT.Juergen Ributzka2014-01-23
| | | | | | | | | | | This patch adds the target analysis passes (usually TargetTransformInfo) to the codgen pipeline. We also expose now the AddAnalysisPasses method through the C API, because the optimizer passes would also benefit from better target-specific cost models.

| | | | | | | | | | | | | | | (and hopefully on Windows). The bots have been down most of the day because of this, and it's not clear to me what all will be required to fix it. The commits started with r153205, then r153207, r153208, and r153221. The first commit seems to be the real culprit, but I couldn't revert a smaller number of patches. When resubmitting, r153207 and r153208 should be folded into r153205, they were simple build fixes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153241 91177308-0d34-0410-b5e6-96231b3b80d8

* Kill ModuleProvider and ghost linkage by inverting the relationship betweenJeffrey Yasskin2010-01-27
| | | | | | | | | | | | | | | | | | | | | | Modules and ModuleProviders. Because the "ModuleProvider" simply materializes GlobalValues now, and doesn't provide modules, it's renamed to "GVMaterializer". Code that used to need a ModuleProvider to materialize Functions can now materialize the Functions directly. Functions no longer use a magic linkage to record that they're materializable; they simply ask the GVMaterializer. Because the C ABI must never change, we can't remove LLVMModuleProviderRef or the functions that refer to it. Instead, because Module now exposes the same functionality ModuleProvider used to, we store a Module* in any LLVMModuleProviderRef and translate in the wrapper methods. The bindings to other languages still use the ModuleProvider concept. It would probably be worth some time to update them to follow the C++ more closely, but I don't intend to do it.

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

* Implement the JIT side of the GDB JIT debugging interface. To enable thisReid Kleckner2009-09-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
