parisc: avoid c23 'nullptr' idenitifier

2024-02-27T21:51:44Z

Starting in c23, this is a reserved keyword, so in the future, using it will start causing build failures: arch/parisc/math-emu/frnd.c:36:23: error: expected ';', ',' or ')' before 'nullptr' Since I can't think of a good replacement name, add a leading underscore to the function argument to avoid this namespace conflict. Apparently all of these arguments are unused. Signed-off-by: Arnd Bergmann Signed-off-by: Helge Deller

parisc: math-emu: Avoid "fmt" macro collision

2021-08-30T08:18:24Z

The printk "fmt" macro was colliding. Rename like the others with a "bits" suffix.

Makefile: Convert -Wimplicit-fallthrough=3 to just -Wimplicit-fallthrough for clang

2019-08-10T19:45:37Z

A compilation -Wimplicit-fallthrough warning was enabled by commit a035d552a93b ("Makefile: Globally enable fall-through warning") Even though clang 10.0.0 does not currently support this warning without a patch, clang currently does not support a value for this option. Link: https://bugs.llvm.org/show_bug.cgi?id=39382 The gcc default for this warning is 3 so removing the =3 has no effect for gcc and enables the warning for patched versions of clang. Also remove the =3 from an existing use in a parisc Makefile: arch/parisc/math-emu/Makefile Signed-off-by: Joe Perches Reviewed-and-tested-by: Nathan Chancellor Cc: Gustavo A. R.

parisc: Fix fall-through warnings in fpudispatch.c

2019-07-31T14:16:43Z

In fpudispatch.c we see a lot of fall-through warnings, but for this file we prefer to not mark the switches and instead keep it in it's original state as it's copied from HP-UX. Fixes: a035d552a93b ("Makefile: Globally enable fall-through warning") Signed-off-by: Helge Deller
