Subject: [hwloc-devel] Status of "Paul's bugs"
From: Paul H. Hargrove (PHHargrove_at_[hidden])
Date: 2012-02-01 16:45:57

A status report as of 13:30 US Pacific time.
Note that all the bugs I reported last night appeared in BOTH 1.3.1 and
1.4 (despite only 1.3.1 in the initial subject lines of each thread).

With the tarball which Jeff Squyres provided off-list I've verified that
the bugs in the following threads appear FIXED.
I have no clue which branches the fixes have been applied to.

+ hwloc-1.3.1 build failure w/ Solaris Studio compilers
Brice added a required "-lm" in the proper place

+ hwloc-1.3.1 install failure w/ older GNU sed
Brice rewrote the install hook not to use sed's "-i" option

+ hwloc-1.3.1 install failures on Solaris-10
Brice and Jeff rewrote docs/ to avoid over-length command lines.

The following two remain, as far as I know, UNRESOLVED:

+ hwloc-1.3.1 "gmake check" failure on Solaris-10/SPARC/gccfss
For this compiler the ffs() implementation is missing from libgcc
Hwloc could either:
1) Detect this compiler at configure time and modify misc.h to pretend
ffs() is missing
2) Document this compiler as broken/unsupported

+ hwloc-1.3.1 assertion failures on Linux/POWER7
Brice has requested more info off-list, which I have provided.
There are actually 2 issues in that thread:
1) XLC appears to be doing bad things w/ the set_affinity code (also
seen by Chris Samuel).
2) Assertion failures, possibly related to IBM's virtualization, and
present w/ both gcc and xlc.

The following two I am NOT expecting fixes for:

+ hwloc-1.3.1 libtool broken on Solaris10-x86
Turned out to be a false-alarm.
libtool does the right thing when the error occurs, but doesn't suppress
the error message

+ hwloc-1.3.1 and 1.4 failures on MIPS64/qemu
Looks very likely to be a compiler bug, or possibly a qemu bug.
I'll provide more info IF I can, but this is very low on my list of
