-Subject: [PATCH] Change container for riscv floating-point state to __riscv_mc_fp_state
-
-Match the struct elements with glibc
-glibc also uses __riscv_mc prefix, some packages like gdb uses that

-Subject: [PATCH] correct the operand specifiers in the riscv64 CAS routines
-
-The operand sepcifiers in a_cas and a_casp for riscv64 were incorrect:
-there's a backwards branch in the routine, so despite tmp being written
-at the end of the assembly fragment it cannot be allocated in one of the
-input registers because the input values may be needed for another trip
-around the loop.
-
-For code that follows the guarnteed forward progress requirements, he
-backwards branch is rarely taken: SiFive's hardware only fails a store
-conditional on execptional cases (ie, instruction cache misses inside
-the loop), and until recently a bug in QEMU allowed back-to-back
-store conditionals to succeed. The bug has been fixed in the latest
-QEMU release, but it turns out that the fix caused this latent bug in
-musl to manifest.
-
-Full disclosure: I haven't actually even compiled musl. I just guessed
-this would fix a bug introducted by the new QEMU behavior, Alistair
-(CC'd) actually checked it fixes the problem. The rest is just
-conjecture.

+
+ reintroduce riscv64 struct sigcontext
+
+ commit ab3eb89a8b83353cdaab12ed017a67a7730f90e9 removed it as part of
+ correcting the mcontext_t definition, but there is still code using
+ struct sigcontext and expecting the member names present in it, most
+ notably libgcc_eh. almost all such usage is incorrect, but bring back
+ struct sigcontext at least for now so as not to introduce regressions.
