Make muser-mode the default for LEON3
2015-09-28 Daniel Cederman <cederman@gaisler.com>
Make muser-mode the default for LEON3
The muser-mode flag causes the CASA instruction for LEON3 to use the
user mode ASI. This is the correct behavior for almost all LEON3 targets.
For this reason it makes sense to make user mode the default.
gcc/
* config/sparc/sparc.opt: Rename mask from USER_MODE to SV_MODE
and make it inverse to change default
* config/sparc/sync.md: Only use supervisor ASI for CASA when in
supervisor mode
* doc/invoke.texi: Document change of default

Fix PowerPC ICE due to secondary_reload ignoring reload replacements
The reason for this PR is that insns emitted by secondary reload
patterns are being generated without taking into account other reloads
that may have occurred. We run into this problem when an insn has a
pseudo that doesn't get a hard reg, and the pseudo is used in a way
that requires a secondary reload. In this case the secondary reload
is needed due to gcc generating a 64-bit gpr load from memory insn
with an address offset not a multiple of 4.

[RS6000] Weak functions may not be file local
A weak symbol defined in the current object file may not turn out to
be the definition used at link time, if other copies of the symbol
exist. This means they can't be considered file local.
