2021-05-11target/riscv: Consolidate RV32/64 16-bit instructionsAlistair Francis
This patch removes the insn16-32.decode and insn16-64.decode decode files and consolidates the instructions into the general RISC-V insn16.decode decode tree. This means that all of the instructions are avaliable in both the 32-bit and 64-bit builds. This also means that we run a check to ensure we are running a 64-bit softmmu before we execute the 64-bit only instructions. This allows us to include the 32-bit instructions in the 64-bit build, while also ensuring that 32-bit only software can not execute the instructions.

2021-05-10i386: split svm_helper into sysemu and stub-only userClaudio Fontana
For now we just copy over the previous user stubs, but really, everything that requires s->cpl == 0 should be impossible to trigger from user-mode emulation. Later on we should add a check that asserts this easily f.e.: static bool check_cpl0(DisasContext *s) { int cpl = s->cpl; #ifdef CONFIG_USER_ONLY assert(cpl == 3); #endif if (cpl != 0) { gen_exception(s, EXCP0D_GPF, s->pc_start - s->cs_base); return false; } return true; } Signed-off-by: Claudio Fontana <cfontana@suse.de> Cc: Paolo Bonzini <pbonzini@redhat.com> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Message-Id: <20210322132800.7470-17-cfontana@suse.de> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2021-05-10i386: separate fpu_helper sysemu-only partsClaudio Fontana
create a separate tcg/sysemu/fpu_helper.c for the sysemu-only parts. For user mode, some small #ifdefs remain in tcg/fpu_helper.c which do not seem worth splitting into their own user-mode module.
