[LLVMdev] comparing .o files from different build trees
I'm trying to write a script for checking whether the compiler recursed
properly.
rkotler at mipsswbrd002:~/slave/recurse3be/build$ find . -name "*.o" -exec
cmp '{}' ../../recurse2be/build/'{}' \; |& tee foo.txt
Is anyone else doing this?
There 2 compilers, recurse 2 and recurse3 that in principle should be
identical.
Obviously if there is date and time information, miscompares can occur.

[LLVMdev] successful full recurse of mips32
...ew recurse directory.
in recurse I copy clang2 from recurse1 to a recurse but name it clang1.
then i build recurse2 again in directory recurse on the mips host (this
time it was built with the second generation clang/llvm).
then use find to diff all the .o files
rkotler at mipsswbrd002:~/slave/recurse2be/build$ find . -name "*.o" -exec
cmp '{}' /home/rkotler/slave1/recurse2be/build/'{}' \; |& tee foo.txt
