- most builds are working
- arm64, amd64, sparc, evbmips64-eb, and armv7hf-el are known to be
stable and work
- mips64-el needs new binutils, in testing
- vax, sh3*, riscv64 and mipse[lb] builds are broken in various ways
* route: ensure IPv4LL routes come last in priority
* DHCP: fix many issues with extending the last lease
* privsep: don't read control group from config in privsep
* privsep: only the master process responds to signals
* privsep: use a socketpair for stderr/stdin rather than dupping /dev/null
* privsep: right limit stdin/stderr/stdout
* privsep: dumping a lease is now run in a sandbox
* options: check if kernel supports INET or INET6 before enabling default
* options: let clientid override a prior duid
* options: allow -1 to represent infinity for requested lease time
* dhcpcd: fix a crash initing a new interface after route overflow
slightly updated in status. x86-64 and sparc and mips64-eb
all appear to work well enough to complete or get well into
an atf run (still going.)
note first ICE segv on sh3
right now. new address-of-packed-member and format-overflow
warnings have new GCC_NO_ADDR_OF_PACKED_MEMBER amd
GCC_NO_FORMAT_OVERFLOW variables to remove these warnings.
apply to a bunch of the tree. mostly, these are real bugs that
should be fixed, but in many cases, only by removing the 'packed'
attribute from some structure that doesn't really need it. (i
looked at many different ones, and while perhaps 60-80% were
already properly aligned, it wasn't clear to me that the uses
were always coming from sane data vs network alignment, so it
doesn't seem safe to remove packed without careful research for
each affect struct.) clang already warned (and was not erroring)
for many of these cases, but gcc picked up dozens more.
- live patching support
- shell completion help
- generally better diagnostic output (less verbose/more useful)
- diagnostics and optimisation choices can be emitted in json
- asan memory usage reduction
- many general, and specific to switch, inter-procedure,
profile and link-time optimisations. from the release notes:
"Overall compile time of Firefox 66 and LibreOffice 6.2.3 on
an 8-core machine was reduced by about 5% compared to GCC 8.3"
- OpenMP 5.0 support
- better spell-guesser
- partial experimental support for c2x and c++2a
- c++17 is no longer experimental
- arm AAPCS GCC 6-8 structure passing bug fixed, may cause
incompatibility (restored compat with GCC 5 and earlier.)
- openrisc support
