[llvm-commits] [PATCH][MIPS] MCJIT for MIPS32

[Jovanovic, Petar]

Hi Andy,

I have just run the test on MacOS, and no regressions with the patch.

Hi Andy,

I have run 'make check' on x86/Linux, and the results were fine. Haven't tested
on Mach-O.

Regards,
Petar

Hi Petar,

Have you tested this on X86 Linux and MachO?

This particular change caught my eye:


===================================================================
--- lib/ExecutionEngine/RuntimeDyld/RuntimeDyld.cpp     (revision 160697)
+++ lib/ExecutionEngine/RuntimeDyld/RuntimeDyld.cpp     (working copy)

       CommonSymbols[*i] = Size;
     } else {
       if (SymType == object::SymbolRef::ST_Function ||
-          SymType == object::SymbolRef::ST_Data) {
+          SymType == object::SymbolRef::ST_Data ||
+          SymType == object::SymbolRef::ST_Unknown) {
         uint64_t FileOffset;
         StringRef SectionData;
         section_iterator si = obj->end_sections();


I have a vague memory of having tried adding the ST_Unknown case there before and having it break one or the other of the above-mentioned platforms.  I can't remember the specifics.  That may have been before I added the explicit common symbol handling.  Unfortunately, I haven't been able to find anything to jog my memory.

Hi everyone

here is a patch that corrects MCJIT functionality for MIPS32 architecture.
The code has been tested on little-endian MIPS32 platform.
