C preprocessor definitions to check for B extension
stnolting opened this issue · comments
Are there any official definitions made by the C/C++ preprocessor to check for the B extension?
I am looking for something like this:
__riscv_compressed -> defined when targeting the C ISA extension.
And accordingly for the B extension:
"__riscv_bitmanip" -> defined when targeting the B ISA extension? 🤔
See https://github.com/riscv/riscv-c-api-doc/blob/master/riscv-c-api.md
__riscv_b is the preferred solution. Some older compilers may support __riscv_bitmanip which is now deprecated.
That was exactly what I was looking for.
Thank you very much!
