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.
