We recently turned on MCJIT in LLVM for Mips target and Linux host.<br>
<br>
On our build bots that run on Mips linux boxes, we got lots of
failures from the normal "make check" from the MCJIT tests but
nobody else in LLVM land sees it because you need to run on Mips
hardware or use Qemu simulating Mips hardware in order to get the
failures.<br>
<br>
In the near future, we will be submitting build slaves to LLVM
nightly builds and then you would see these tests passing or not.<br>

<div>It is fixing issues with MCJIT for MIPS32. MIPS supports
static relocation model for MCJIT, and this patch enables
successful execution for these cases.</div>

</div>
<div>No test cases have been added, because LLVM already
contains tests for MCJIT.</div>

<div>What does it correct? Is it fixing a bug, adding
functionality? We need more information about what you're
trying to do in order to have the context for reviewing a
patch.

<div>Are all of these changes really a single patch?</div>

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