Hi,
MULTILIB_OPTIONS containing options defined in DRIVER_SELF_SPEC seemed
to be fine in GCC46 but fail in GCC47.
For example, I have:
xap.h:
#define DRIVER_SELF_SPECS \
"%{help:-v} %<help", \
"%{mno-args-span-regs-and-mem:-mno-split-args}
%<mno-args-span-regs-and-mem", \
"%{mno-inline-block-copy-mode:-mno-block-copy}
%<mno-inline-block-copy-mode", \
"%{mpu:-mno-block-copy -mfunction-ptr-pi} %<mpu"
t-xap:
MULTILIB_OPTIONS= msmall-mode/mpu
However, while building GCC I get that xgcc cannot understand -mpu:
Running configure in multilib subdir mpu
pwd:
/home/pm18/p4ws/pm18_binutils/bc/main/result/linux/intermediate/FirmwareGcc47Package/xap-local-xap

xgcc: error: unrecognized command line option '-mpu'
What happened in GCC47 for this to occur?
Cheers,
