676198 - Test suite for elfhack

Status: NEW

(Firefox Build System :: General, enhancement, P3)

Description

[Mike Hommey [:glandium]]

As mentioned in bug 674888, we need a test suite to keep track of linker-specific issues. The current check is good enough to assert make package won't fail with the toolchain being used when building, but doesn't check that elfhack itself doesn't regress on different toolchains.

If you're interested in making synthetic ELF files for testing, I wrote a class for that for Breakpad unit tests recently:
http://code.google.com/p/google-breakpad/source/browse/trunk/src/common/linux/synth_elf.h
http://code.google.com/p/google-breakpad/source/browse/trunk/src/common/linux/synth_elf.cc

It builds on jimb's general purpose test assembler stuff:
http://code.google.com/p/google-breakpad/source/browse/trunk/src/common/test_assembler.h

You can see a few examples of both here:

In fact, elfhack may already have all it takes to do that.
