math.h: fma(x,y,z) inlined to __d_fma(x,y,z) causes compiler failure
| Reported by: | Stuart Swales (8827) | Severity: | Normal |
| Part: | RISC OS: C/C++ toolchain | Release: | |
| Milestone: | Status | Fixed |
Details by Stuart Swales (8827):
//Norcroft RISC OS ARM C vsn 5.86 [10 Feb 2021]
//Fatal internal error: show_inst_dir(0XD5)
//Internal inconsistency: either resource shortage or compiler fault. If you
//cannot alter your program to avoid this failure, please contact your supplier
Workaround is to enclose use of fma in parentheses to avoid the macro expansion.
