Bug ID: 200262
Summary: [ports]Universal optimization patch
Product: Ports & Packages
Version: Latest
Hardware: Any
OS: Any
Status: New
Severity: Affects Many People
Priority: ---
Component: Ports Framework
Assignee: portmgr at FreeBSD.org
Reporter: sasamotikomi at gmail.com
CC: freebsd-ports-bugs at FreeBSD.org
I offer use universal optimization submenu(or as section additional
"development") and automatic detect instruction of processor instead
understandably options "Optimization" or single option for one instruction
(MMX/SSE):
Example:
_________________________________Development_____________
Optimization +->(mean submenu also if possible use color and legend such: Green
- all possible(or/and recommended) optimization is used, Yellow few
optimization is used some not used by default, Red some enabled optimization is
not supported by your processor but enabled, Gray optimization is not used)
Architecture:
i386(x86_32) () amd64(x86_64) (*) arm () arm64() mips() mips64() powerpc32()
powerpc64() sparc64()
(useless until cross compilation isn't supported
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=200167 )
Mircoachitecture(better use real architecture name, if abbreviation of compiler
is not obvious):
native()
(show inly if i386 selected):
AMD: Intel: Winchip: VIA:
k6() i386() winchip-c6() c3()
k6-2() i486() winchip2() c3-2()
k6-3() i586()
athlon() pentium()
athlon-tbird() pentium-mmx()
athlon-4() pentiumpro()
athlon-xp() i686()
athlon-mp() pentium2()
geode() pentium3()
pentium3m()
pentium-m()
pentium4( )

(x86_64)
AMD: Intel:
k8() nocona()
opteron() core2()
athlon64() nehalem()
athlon-fx() westmere()
k8-sse3() sandybridge()
opteron-sse3() ivybridge()
athlon64-sse3() haswell()
amdfam10() broadwell()
barcelona(*) bonnell()
bdver1() silvermont()
bdver2() knl()
bdver3()
bdver4()
btver1()
btver2()
Optimization level: Not() | -O() -O2() -O3(*) -Os() -0[_]()
Cache size [] l1[___] l2[__] l3 [__] l4[___]
Instructions(don't show unavailable instructions for processor or ports):
MMX[x]
3DNow![]
SSE[x] SSE2[x] SSE3[x] SSE4[x] SSE4.1 [x] SSE4.2 [x] SSE4A[]
AES[x]
AVX[] AVX2[] AVX512[] AVX512PF[] AVX512ER[] AVX512CD[]
SHA []
PCLMUL[]
FSGSBASE[]
RDRND[]
F16C[]
FMA[] FMA4[]
XOP[]
LWP []
ABM[]
BMI[] BMI2[]
FXSR[]
XSAVE[] XSAVEOPT[]
LZCNT[]
RTM[]
MPX[]
It's fix or help avoid many issue with wrong optimization flags such SSE2/SSE3
on i386 or 3dnow! on Intel processor or AMD FX:
