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] comparing .o files from different build trees
I have a tool called 'diffdump' for pretty much exactly this: https://github.com/garious/diffdump I originally wrote it to compare the objdump output between every object file in two directories, where one directory has objects compiled with LLVM and the other with GCC. That usage is described here: https://github.com/garious/diffdump#more-diffdump-examples Let me know if you have any questions. -Greg On Thu, Apr 3, 2014 at 10:43 AM, reed kotler <rkotler at mips.com> wrote:> 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. > > _______________________________________________ > LLVM Developers mailing list > LLVMdev at cs.uiuc.edu http://llvm.cs.uiuc.edu > http://lists.cs.uiuc.edu/mailman/listinfo/llvmdev >
I've realized that it's necessary to build the recursed compiler in the
same directory as it's previous generation (after moving the previous
somewhere else) before doing the diff since the names of various
generated files are embedded in the .o somtimes.
For example:
rkotler at mipsswbrd002:~/slave/recurse2be/build$ diff ../../tmp/1 ../../tmp/2
2c2
< ./tools/clang/lib/AST/Release+Asserts/ASTDumper.o: file format
