[Minios-devel] [UNIKRAFT PATCH v2 0/6] Interrupt-safe compile units

[Simon Kuenzer <simon.kuenzer@xxxxxxxxx>]

Prepares the build system to compile units that are safe to get
called from interrupt/trap context. For this purpose, a new
reserved variant is introduced: `isr`.
Whenever this variant is given to a source file, the build system
instructs the compiler to avoid using extended machine units
which aren't saved before entering interrupt context (e.g.,
floating point units, vector units):
 LIBNAME_SRCS-y += $(LIBNAME_BASE)/handler.c|isr

Chnages v2:
 - support/build/Makefile.rules
   Make sure that the results of vprefix_* calls are stripped
 - Makefile.uk: Move the GCC flag `-fms-extensions` from Arm64
   to CFLAGS

Simon Kuenzer (6):
  build: buildrule: Strip arguments
  build: Forward variant to build rules
  build: Rename C++ buildrule to buildrule_cxx
  build: Introduce COMPFLAGS(-y) and ARCHFLAGS(-y)
  arch/*, build: Introduce reserved `isr` variant
  doc: Document reserved `isr` variant
