- Subject: [PATCH, ARM] soft/hard-float preprocessor symbol
Hi, this patch adds built-in preprocessor symbols __ARM_PCS,
__ARM_PCS_VFP to indicate the current soft/hard-float calling
convention, as described in the draft ACLE.
If approved, please help to apply to trunk, as I don't have commit
rights yet.
Thanks,
Chung-Lin
