Hi Chris!
I currently have code like this in c/src/lib/libbsp/x86_64/amd64/Makefile.am:
librtemsbsp_a_SOURCES +=
../../../../../../bsps/x86_64/amd64/interrupts/handlers.c
# XXX: Needed to use GCC "interrupt" attribute directives - can we
pass these
# flags only for the handlers.c source file (compile to an object
file first and
# then link with the rest for librtemsbsp.a?)
librtemsbsp_a_CFLAGS = -mgeneral-regs-only
The CFLAGS arg is required to allow us to use
"__attribute__((interrupt))" to setup interrupt handlers in C. (See
[1] and ctrl+f "interrupt" for more.)
Is there a way to not force the CFLAGS for _all_ of librtemsbsp, but
to limit it only to handlers.c?
If not, is the above code something that would be acceptable to have upstream?
