Hi Alex, Hi Jeff, Hi Richard,
The clzsi2/bsch patterns in the MN10300 backend do not work. There
are two problems - firstly the starting bit-search position for the
BSCH instruction is not set. Secondly the BSCH instruction returns
the bit position of the highest set bit, not the number

I cannot bootstrap SPARC64/Solaris anymore though:
/nile.build/botcazou/gcc-head/sparc64-sun-solaris2.9/./gcc/xgcc

I committed the following patch as approved in the PR thread.

Hi,
just for those who are interested, this is quick&dirty patch adding another

missing by limiting those to early pass.

The maintainers of GCC in Fedora have split out libgnat.a and libgnarl.a to a

This causes Gnatmake to crash when it tries to find the d

The use of #ifndef seems to imply that this is a target macro, to be
defined in libgcc_tm.h. In that case it should be documented, and
poisoned in system.h under the "only used for code built for the target"
case, and this:

Hi Richard,
The clzsi2/bsch patterns in the MN10300 backend do not work. There

BSCH instruction is not set.
Yes it is. What do you think that "unused" second operand does?
That actually works ? Gross!
