Hi,
|
|
|
|
by recent tests in gcc.target/i386 I noticed that testcase
|
|
float128-2.c failed on executation. This failure is caused by
|
|
incompatible bitfield-structure definition in soft-fp/quad.h for
|
|
enabled ms-bitfields layout.
|
|
|
|
Patch marks those structures to be 'gcc_struct' for mingw targets.
|
|
|
|
ChangeLog
|
|
|
|
2012-02-27 Kai Tietz <ktietz@redhat.com>
|
|
|
|
* soft-fp/quad.h: Mark bitfield-structures as gcc_struct.
|
|
|
|
Regression tested for i686-w64-mingw32, x86_64-w64-mingw32, and
|
|
x86_64-unknown-linux-gnu for all languages (including Ada + Obj-C++).
|
|
Ok for apply?
|
|
|
|
Regards,
|
|
Kai
