config.gcc (*-*-vxworks*): Add TARGET_VXWORKS7=1 to tm_defines for all vxworks7 targets.
2017-06-26 Jerome Lambourg <lambourg@adacore.com>
Olivier Hainque <hainque@adacore.com>
* config.gcc (*-*-vxworks*): Add TARGET_VXWORKS7=1 to tm_defines
for all vxworks7 targets.
* config/vxworks.h (TARGET_VXWORKS7): If not defined, define to 0.
(VXWORKS_ADDITIONAL_CPP_SPEC): Alternative definition for VXWORKS7.
(VXWORKS_LIBS_RTP, VXWORKS_LIBS_RTP_DIR): New macros, allowing
variations for VX6/VX7 and 32/64bits later on in ...
(VXWORKS_LIB_SPEC): Leverage new macros.
(VXWORKS_OS_CPP_BUILTINS): Define _VSB_CONFIG_FILE for VXWORKS7,
as well as _ALLOW_KEYWORD_MACROS when "inline" is not a keyword.
