  qemu-doc: Amend MIPS-related items (2018-08-14 19:59:03 +0200)

----------------------------------------------------------------
MIPS queue for QEMU upstream, August 14, 2018

This is the first part of nanoMIPS support for QEMU. It contains
various fixes and improvements that are related to nanoMIPS support,
or are discovered while working on nanoMIPS support. Most of them are
fairly simple changes, but each of them has its own significance and
importance for nanoMIPS support.

The second part that contains QEMU support for core nanoMIPS
functionality will remain under review for some time.

The third part that mainly contains Linux user support will likely
remain under review for some longer period.

Hi; this fails to build on clang:

/home/petmay01/linaro/qemu-for-merges/target/mips/translate.c:1749:20:
error: unused function 'gen_op_addr_addi' [-Werror,-Wunused-funct
ion]
static inline void gen_op_addr_addi(DisasContext *ctx, TCGv ret, TCGv base,
                   ^
/home/petmay01/linaro/qemu-for-merges/target/mips/translate.c:1921:20:
error: unused function 'check_xnp' [-Werror,-Wunused-function]
static inline void check_xnp(DisasContext *ctx)
                   ^
2 errors generated.

The functions do appear to be genuinely unused.

thanks

These functions are used in the patches that follow in nanoMIPS series, but not submitted in this pull request.

Ok, I will reorganize the patches so that there is no such case, and will send the new pull request soon.

Do we require that bisect works for clang builds too (meaning that after each patch, clang build must be success)?

Aleksandar

Yes, please. (As usual with breaking-bisection, if you get it wrong by
accident we may well not notice, but it's worth trying to get right.)
