This is a rework of: http://sources.redhat.com/ml/gdb-patches/2005-05/msg00405.html Hopefully this patch will be more acceptable. 2005-05-17 Joel Brobecker <brobecker@adacore.com> * alpha-tdep.c (fp_register_zero_p): New function. (fp_register_sign_bit): New function. (alpha_next_pc): Add support for floating-point control instructions. Tested on alpha-tru64 5.1a with no regression. I'll try to contribute an asm test asap. One remark: For zero_mask in fp_register_zero_p(), Richard suggested to use "((LONGEST) 1 << 63) - 1", but that triggered an overflow warning from GCC. So I reverted to using the xor binary operator. Daniel said that many things would break in GDB with 128-bit types, so I think the xor is quite acceptable for now. OK to commit? Thanks, -- Joel
