lib:
libasan is disabled currently (haven't tried yet)
new stuff:
cc1objcplus
collect2 -- need to re-introduce?
libcilkrts
libmpx
liboffloadmic
libvtv
libitm
other changes to look at:
Index: gcc/targhooks.c
vs new binutils
+ doc/gcov-tool.1
arch/feature list. anything not here has been switched already:
tools: does build.sh tools work?
kernels: does a kernel run?
libgcc: does libgcc build?
native-gcc: does a full mknative-gcc complete?
make release: does build.sh release complete?
runs: does the system boot with a full world?
atf: does atf run / compare well
architecture tools kernels libgcc native-gcc make release runs atf

architecture tools kernels libgcc native-gcc make release runs atf
[2] - -O2 and -Os kernels hang, -O1 SIR reset
-- may be a SMP issue; ultra10 works, ultra45 SMP does not
-- try sb2000 (particularly with UP kernel. u45 UP is shitty.)
[3] - MKCOMPAT=no enabled currently, infact OABI seems to be broken. the docs say it was only deprecated, but the options make broken stuff.
[5] - sh3eb tries to use sh specific atomic config which doesn't work, has hand edited mknative output
[6] - crtbeginS.o builds incorrectly with GCC 5.3 and -O2. a hack for -O1 has been added.
[8] - sgimips64 release build fails, mdsetimage'd gz'd kernels don't get built?
[10] - needs to be re-merged with GCC 5.3 versions of these not-merged-to-mainline-gcc ports.
[13] - builds tested:
- m68k: mvm68k amiga atari
- earm : shark evbarm*
- mipseb: sgimips evbmips
- mipsel: evbmips
- mips64eb: sgimips[fail] evbmips
- mips64el: evbmips
[14] - machines tested:
- sparc ss20 (OK)
- sparc64 ultra45 (FAIL), ultra10 (OK), sb2000 (OK UP, FAIL SMP.)
- powerpc pegasosII (OK)
- alpha UP1000 (OK)
- arm shark (OK)
- evbmips gxemul MALTA
- had to implement some MIPS32 in gxemul to make this work
- pmax gxemul (OK)
- sgimips O2 (OK kernel -- but my O2 is not stable)
- i386/amd64 (OK)
- hppa (OK)
- amiga (OK)
[15] - vax -- switched to GCC 5.3 already as it is less broken
- ssh is broken, was broken with 4.8
- there are too many -O0's we added because of mis-handled rtl
- the eh_frame stuff is probably busted, but it never worked?
[16] - kernels tested:
- m68k: amiga
