powerpc: Make setjmp/longjmp signature standard

2020-04-01T03:30:51+00:00

Declaring setjmp()/longjmp() as taking longs makes the signature non-standard, and makes clang complain. In the past, this has been worked around by adding -ffreestanding to the compile flags. The implementation looks like it only ever propagates the value (in longjmp) or sets it to 1 (in setjmp), and we only call longjmp with integer parameters. This allows removing -ffreestanding from the compilation flags.

powerpc: Add attributes for setjmp/longjmp

2019-09-11T23:26:59+00:00

The setjmp function should be declared as "returns_twice", or bad things can happen[1]. This does not actually change generated code in my testing. The longjmp function should be declared as "noreturn", so that the compiler can optimise calls to it better. This makes the generated code a little shorter. 1: https://gcc.gnu.org/onlinedocs/gcc/Common-Function-Attributes.html#index-returns_005ftwice-function-attribute Signed-off-by: Segher Boessenkool Signed-off-by: Michael Ellerman Link: https://lore.kernel.org/r/c02ce4a573f3bac907e2c70957a2d1275f910013.1567605586.git.segher@kernel.crashing.org

powerpc: Move include files to arch/powerpc/include/asm

2008-08-04T02:02:00+00:00

from include/asm-powerpc. This is the result of a mkdir arch/powerpc/include/asm git mv include/asm-powerpc/* arch/powerpc/include/asm Followed by a few documentation/comment fixups and a couple of places where was being used explicitly. Of the latter only one was outside the arch code and it is a driver only built for powerpc. Signed-off-by: Stephen Rothwell Signed-off-by: Paul Mackerras
