Bug ID: 81831
Summary: -Wno-psabi is not documented
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: other
Assignee: unassigned at gcc dot gnu.org
Reporter: munroesj at gcc dot gnu.org
Target Milestone: ---
The online GCC documentation mentions psABI though out the document, but
section "3.8 Options to Request or Suppress Warning" does not describe or even
mention -Wno-psabi.
This may be an issues for some of the tests I am writing which are consistently
generating the warning:
In function 'check_union128':
/home/sjmunroe/work/gcc-trunk/gcc/gcc/testsuite/gcc.target/powerpc/m128-check.h:89:1:
note: the ABI of passing aggregates with 16-byte alignment has changed in GCC 5
I am not sure what this will do if someone asserts -Werror.
So it may be appropriate to suppress this warning for ./testsuite/gcc.target/
but when I searched the documentation I could not find any obvious way to do
that.
Segher tells me that -Wno-psabi will suppress this warning, but this is not
documented any where I can find.
