This patch attempts to address this. Built and tested on
i686-pc-linux-gnu
and as cross version for mmix-mmixware (and verified that the same
failure
cause applies to the other mentioned architectures). The previous
version
was simply overdoing its job.
One thing I'd like to note before any complaints come up: A side effect
of
the change is that on a sequence like
.section .xyz, "a"
.section .xyz, "a", @progbits
a warning will now be issued on the second directive, even though
implicitly
the missing section type in the first will (at a late stage during
assembly)
be set to SHT_PROGBITS, too. I consider this warning valid, though,
for
consistency reasons (one shouldn't use both implicit and explicit
setting of
the type).

Hi Guys,

>>>manually build them individually?
As has already been said the only real mechanism to test the
architecture independent parts of the tools is the brute force approach
- build and check as many different targets as you can and look for
regressions.

Interesting script. I use makefiles myself but to a similar effect.
There were several targets in your list which I was not testing, so I
have added them to my framework. I also noticed that your list does not
include these targets which you might want to add: crx-elf, iq2000-elf,
msp430-elf and xtensa-elf.
Cheers
Nick

No, all that does is compile all (well, most) of the bfd backends. Gas
isn't multi-architecture, so you won't be testing much of gas. I use

I believe the correct answer to that question is to add
"--enable-targets=all" to your configure line. You still need to specify
--target=XXX to select which one is the default.

I'll look into these. A general question, though: For changes like this
(in the architecture independent parts), is there any mechanism to
build/test all (default) architectures without having to manually build
them individually?

Unfortunately this patch appears to introduce quite a few new testsuite
failures in other toolchains. In particular I found lots of failures of
the new section5 test because it only checks for REL in the output and
does not include RELA. (This affected toolchains such as:
alpha-linux-gnu and sh-elf).
Other toolchains had even more difficulties. The patch introduced 51
new unexpected failures for GAS tests and 47 new unexpected failures for
LD tests for the mmix-mmixware toolchain. The mips64-linux toolchain
had 13 and 15 new unexpected failures respectively, and the
sparc64-linux-gnu toolchain has 21 and 9 new failures.
Please could you investigate and resolve these issues and then resubmit
your patch ?
Cheers
