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.
Existing SHA1 digests verified, all found to be the same on the
machine holding the existing distfiles (morden). Existing SHA1
digests retained for now as an audit trail.
Object file converter
This utility can be used for converting object files between COFF/PE,
OMF, ELF and Mach-O formats for all 32-bit and 64-bit x86 platforms.
Can modify symbol names in object files. Can build, modify and
convert function libraries across platforms. Can dump object files
and executable files. Also includes a very good disassembler
supporting the SSE4, AVX, AVX2, AVX512, FMA3, FMA4, XOP and Knights
Corner instruction sets. Source code included (GPL).
This release is a bug-fix release, containing fixes for regressions in
GCC 4.9.1 and 4.9.0 relative to previous releases of GCC.
6 changes and 8 documentation fixes.
- to make pkglint clean, change directory organization, using BUILD_DIR= src etc.
- Add LICENSE= gnu-gpl-v2
- Use SUBST instead of ${SED} at do-install: target
- Newly installs example files
- (invocation without argument gives error as
Pass 1: Error: Cannot open file: 'test.m65'
but it is the same as prev. version and user should give input)
(upstream) Update 1.04 to 1.06
------------------------------
October 10, 2003
version 1.05 - added new directives .BANK, .SET 6, and .OPT LIST/NO LIST;
Preliminary support for .ATR disk images and the Atari++
emulator memory snapshots;
March 17, 2009
version 1.06 - allow negative offsets with .SET 6 directives; allow arithmentic
expressions in REPEAT blocks; Better detection of resized labels;
Fixed a buffer overflow problem; Added -l option to allow label output;
Compiling Windows executable with mingw
(pkgsrc)
- Instead of
"very evil hack to override CC, doing it via CONFIGURE_ENV doesn't work",
use CONFIGURE_ARGS
(upstream)
