disassembled bugpoint output
Using llvm 2.3, and llvm-gcc 4.2-2.3-x86-linux-RHEL4, I get a problem with the
Mips backend. I am basing my own backend on this one, so tried a test with it
first. A simple program outputs "Hello world", creates a variable and counts to
5.
Running through instructions in example at the bottom of
http://www.llvm.org/docs/GettingStarted.html I run into trouble at step 6,
running llc with the argument -march=mips.
I have run bugpoint to reduce and llvm-dis on the output, and the problem seems
to be in returning an i32. (assuming I understand the system correctly!)
When running llc normally, I get the following error:
[EMAIL PROTECTED] llvm]$ llc hello.bc -f -o hello.s -march=mips
terminate called after throwing an instance of 'std::bad_alloc'
what(): St9bad_alloc

Any ideas?
