gcc/ada/ 2011-07-14 Mikael Pettersson * gcc-interface/Makefile.in: Add support for m68k-linux. * system-linux-m68k.ads: New file based on system-linux-ppc.ads and system-vxworks-m68k.ads. * s-memory.adb (Gnat_Malloc): New wrapper around Alloc, returning the memory address as a pointer not an integer. Add Gnat_Malloc -> __gnat_malloc export. * s-memory.ads: Remove Alloc -> __gnat_malloc export. --- gcc-4.5.3/gcc/ada/gcc-interface/Makefile.in.~1~ 2011-02-08 23:56:06.000000000 +0100 +++ gcc-4.5.3/gcc/ada/gcc-interface/Makefile.in 2011-07-14 09:57:38.000000000 +0200 @@ -1887,6 +1887,34 @@ ifeq ($(strip $(filter-out arm% linux-gn LIBRARY_VERSION := $(LIB_VERSION) endif +ifeq ($(strip $(filter-out m68k% linux%,$(arch) $(osys))),) + LIBGNAT_TARGET_PAIRS = \ + a-intnam.ads. -- +-- -- +-- GNAT was originally developed by the GNAT team at New York University. -- +-- Extensive contributions were provided by Ada Core Technologies Inc. -- +-- -- +------------------------------------------------------------------------------ + +package System is + pragma Pure; + -- Note that we take advantage of the implementation permission to make + -- this unit Pure instead of Preelaborable; see RM 13.7.1(15).
