Bug ID: 68602
Summary: i386: -mtune/arch options not all output by -v --help
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: andi-gcc at firstfloor dot org
Target Milestone: ---
gcc -v --help does not output all the possible options for -mtune=/-march=
For example corei7-avx is missing for arch, which is Sandy Bridge. tune is also
mising all cpu names
-march=CPU[,+EXTENSION...]
