We should not expand call arguments in between flags reg setting and
flags reg using instructions, as it may expand with flags reg
clobbering insn (ADD in this case).
Attached patch moves expansion out of the link. Also, change
zero-extension to non-flags reg clobbering sequence in case we perform
zero-extension with and.

(NetBSD/mips64 progress further with gsed)
Adding gsed as a tool creates circular dependencies if pkgsrc gcc is used
as the bootstrap compiler.
Pointed out by jperkin, sorry.
This is a somewhat blind commit. I've long had issues on various platforms
with libgcc getting misconfigured (on netbsd/mips,arm,powerpc), for example
build failures see:
http://mail-index.netbsd.org/port-mips/2017/06/21/msg000832.html
testing GCC 7.1 with netbsd/mips64el I got a lot further using it, but
still didn't complete the build. It took hours to reach this failure,
so I'd rather blindly commit the same change in the hopes it might help
other architectures.
on platforms which do not include driver-arm.o in gcc/config.host, and do
not have this function. such as netbsd/arm.
an alternative would be to add driver-arm.o for the netbsd/arm case too, but
it would be diverging from netbsd base gcc, and /proc/cpuinfo which is needed
for this function to do anything useful is empty at least on my machine.
(I still can't complete a build on ARM)
No change for i386/amd64, but arm needs additional extra_objs to build.
Mistake was in a netbsd-specific part of configure as well.
Thanks to Richard Earnshaw and ktkachov at GCC for finding the problem.
because we unconditionally disable libssp, we don't need the workaround
for ssp.h not found, so we can remove that part of that makefile.
bump gcc5 PKGREVISION
bump gcc5-libs PKGREVISION further than gcc5.
Changelog:
Target Specific Changes
IA-32/x86-64
GCC now supports the Intel CPU named Skylake with AVX-512 extensions
through -march=skylake-avx512. The switch enables the following ISA
extensions: AVX-512F, AVX512VL, AVX-512CD, AVX-512BW, AVX-512DQ.
The find-prefix infrastructure was required in a pkgviews world where
packages installed from pkgsrc could have different installation
prefixes, and this was a way for a dependency prefix to be determined.
Now that pkgviews has been removed there is no longer any need for the
overhead of this infrastructure. Instead we use BUILDLINK_PREFIX.pkg
for dependencies pulled in via buildlink, or LOCALBASE/PREFIX where the
dependency is coming from pkgsrc.
Provides a reasonable performance win due to the reduction of `pkg_info
-qp` calls, some of which were redundant anyway as they were duplicating
the same information provided by BUILDLINK_PREFIX.pkg.
Changelog:
GCC 5.2
This is the [42]list of problem reports (PRs) from GCC's bug tracking
system that are known to be fixed in the 5.2 release. This list might
not be complete (that is, it is possible that some PRs that have been
fixed are not listed here).
Target Specific Changes
IA-32/x86-64
* Support for new AMD instructions monitorx and mwaitx has been
added. This includes new intrinsic and built-in support. It is
enabled through option -mmwaitx. The instructions monitorx and
mwaitx implement the same functionality as the old monitor and
mwait instructions. In addition mwaitx adds a configurable timer.
The timer value is received as third argument and stored in
register %ebx.

The GNU Compiler Collection (GCC) includes front ends for C, C++, Objective-C,
Fortran, Java, and Go, as well as libraries for these languages (libstdc++,
libgcj,...). This package provides the snapshot release of version 5.
On NetBSD a working cabsl function must be present in libm to build gfortran.
This has been added to -current on 2014/10/10 and to NetBSD7 on 2014/10/13.
