* Remove the '-disable-scheduling' flag and replace it with the 'source' option ofBill Wendling2010-01-231-6/+0
| | | | | | | | | | the '-pre-RA-sched' flag. It actually makes more sense to do it this way. Also, keep track of the SDNode ordering by default. Eventually, we would like to make this ordering a way to break a "tie" in the scheduler. However, doing that now breaks the "CodeGen/X86/abi-isel.ll" test for 32-bit Linux. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94308 91177308-0d34-0410-b5e6-96231b3b80d8
* Changes from review:Bill Wendling2009-12-181-0/+6
| | | | | | | | | | | | - Move DisableScheduling flag into TargetOption.h - Move SDNodeOrdering into its own header file. Give it a minimal interface that doesn't conflate construction with storage. - Move assigning the ordering into the SelectionDAGBuilder. This isn't used yet, so there should be no functional changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@91727 91177308-0d34-0410-b5e6-96231b3b80d8
* Implement the JIT side of the GDB JIT debugging interface. To enable thisReid Kleckner2009-09-201-1/+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.
