Bug ID: 58286
Summary: Need option to make incompatible pointer types into
compiler errors
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: debug
Assignee: unassigned at gcc dot gnu.org
Reporter: ryao at gentoo dot org
Created attachment 30733
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=30733&action=edit
Sample program that illustrates warning that cannot be selectively converted
into an error
Commandline options to change certain warnings into error messages are useful
when designing autotools checks. -Werror can be used for this, but warnings
like "warning: SSE instruction set disabled, using 387 arithmetics [enabled by
default]" will cause -Werror to make autotools checks that should succeed fail.
That broke an autotools check against the Linux kernel API in the ZFSOnLinux
SPL.
I have attached a sample program that demonstrates the warning that needs to be
made into an error for the autotools check to succeed. Clang supports
-Werror=incompatible-pointer-types, which selectively converts the warning into
an error. GCC does not appear to support that option under that name or any
other.
