New Revision: 5224
URL: https://tracker.coreboot.org/trac/coreboot/changeset/5224
Log:
Various changes to the buildsystem:
- Single instance of the CC build rule in Makefile, instantiated as
necessary
- Remove manual static.o and option_table.o rules, they're now covered
by those instances of the CC build rule
- Normalize object file paths, so it can be $(obj)/option_table.o
instead of $(obj)/arch/i386/../../option_table.o now
- Add -pipe to compiler flags. It might be detrimental on rare scenarios
(building with extremly high disk bandwidth, eg. RAM disk), but it
significantly helps on win32 (which seems to cache less aggressively
than most unix-alikes)
- Silence stderr on hostname and domainname invocations (cosmetic fix
for cygwin)
- Test for -Wa,--divide functionality of the target compiler (taken from
abuild). It might be possible to remove most patches in crossgcc with that.
- Report build of failover.inc and romstage.inc
