With the current code, the QEMU TLB is setup to match the read/write mode of the MMU fault. This means when read access is done, the page is setup in read-only mode. When the page is later accessed in write mode, an MMU fault happened, and the page is switch in write-only mode. This flip-flop causes a lot of calls to the MMU code and slow down the emulation. This patch changes the MMU emulation, so that the QEMU TLB is setup to match the UTLB protection key. This impressively increase the speed of the emulation.

There is an ITLB access violation if SR_MD=0 (user mode) while the high bit of the protection key is 0 (priviledge mode). Signed-off-by: NAurelien Jarno <aurelien@aurel32.net>

tlb_set_page() doesn't need addresses with offset, but simply the page aligned addresses. Signed-off-by: NAurelien Jarno <aurelien@aurel32.net>

The mem_idx is wrongly computed. As written in target-sh4/cpu.h, mode 0 corresponds to kernel mode (SR_MD = 1), while mode 1 corresponds to user mode (SR_MD = 0). Signed-off-by: NAurelien Jarno <aurelien@aurel32.net>

Compilation for arm (native or cross) results in this warning: fpu/softfloat-native.c: In function ‘float64_round_to_int’: fpu/softfloat-native.c:387: error: control reaches end of non-void function float64_round_to_int uses special assembler code for arm and has no explicit return value. As there is no obvious reason why arm should need special code, all fpu related conditionals were removed. The remaining code is standard (C99) and compiles for arm, too.

There are places, like brcond2, where we know that the destination of a forward branch will be within 127 bytes. Add the R_386_PC8 relocation type to support this. Add a flag to tcg_out_jxx and tcg_out_brcond* to enable it. Set the flag in the brcond2 label_next branches; pass along the input flag otherwise.

Fix .rel.plt sections in the output to not only include .rel.plt sections from the input but also the .rel.iplt sections and to define the hidden symbols __rel_iplt_start and __rel_iplt_end around .rel.iplt as otherwise we get undefined references to these when linking statically to a multilib libc.a. This fixes the static build under i386. Apply similar logic to rela.plt/.iplt and __rela_iplt/_plt_start/_end to fix the static build under amd64.

Commit a0f291fc has enabled -fstack-protector-all on all targets, as the configure test is bogus. GCC only emits a warning and not an error if this option is not supported, so the configure scripts doesn't detect the problem. This patch changes the configure script to try the various flags with -Werror in addition to catch the possible warnings. Signed-off-by: NAurelien Jarno <aurelien@aurel32.net>
