* lib/target-supports.exp (check_effective_target_rdrand): New proc.
the new effective-target keyword needs documenting in sourcebuild.texi.
Attached patch adds the missing documentation.
It looks like this in gccint.info:
...
7.2.3.10 Other hardware attributes
..................................
'avx'
Target supports compiling 'avx' instructions.
<SNIP>
'divmod_simode'
Target supporting hardware divmod insn or divmod libcall for
SImode.
'rdrand'
Target supports i386/x86-64 insn rdrand.
...
OK?
Thanks,
- Tom
