This patch makes some minor cleanups to eBPF options documented in
invoke.texi:
- Delete some vestigal docs for removed -mkernel option
- Add -mbswap and -msdiv to the option summary
- Note the negative versions of several options
- Note that -mcpu=v4 also enables -msdiv.
gcc/
* doc/invoke.texi (Option Summary): Remove -mkernel eBPF option.
Add -mbswap and -msdiv eBPF options.
(eBPF Options): Remove -mkernel. Add -mno-{jmpext, jmp32,
alu32, v3-atomics, bswap, sdiv}. Document that -mcpu=v4 also
enables -msdiv.
