[cfe-dev] clang Unexpected output

[James Courtier-Dutton via cfe-dev]

Hi,

When I type the command:
clang-5.0 -c -o s.o stdio.h     (note: stdio.h taken from /usr/include/... )

This creates some output in s.o
The problem is that I don't know what format it is.
objdump cannot read it.

Please can someone tell me what format that file is, and which
clang/llvm tool can be made to read it?

Kind Regards

James
