Summary: [4.7 regression] options.c doesn't compile on SPARC
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: ro@gcc.gnu.org
CC: ebotcazou@gcc.gnu.org, jsm28@gcc.gnu.org
Host: sparc-sun-solaris2.*
Target: sparc-sun-solaris2.*
Build: sparc-sun-solaris2.*
As already reported by Art Haas on the gcc list, SPARC bootstrap is broken
since
Joseph's recent sparc option patch:
options.c:753:3: error: enum conversion in initialization is invalid in C++
[-Werror=c++-compat]
options.c:753:3: error: (near initialization for
'global_options_init.x_sparc_cpu_and_features') [-Werror=c++-compat]
options.c:755:3: error: enum conversion in initialization is invalid in C++
[-Werror=c++-compat]
options.c:755:3: error: (near initialization for
'global_options_init.x_sparc_cpu') [-Werror=c++-compat]
The lines in question are:
0, /* sparc_cpu_and_features */
0, /* sparc_std_struct_return */
0, /* sparc_cpu */
Since I could make no sense of the options machinery, I've added
options.o-warn = -Wno-error
to gcc/Makefile.in as a workaround.

That did the trick, together with a similar change in sparc.c. I'll submit the patch shortly. Thanks. Rainer ^ permalink raw reply [flat|nested] 6+ messages in thread
