2021-05-02target/mips: Restrict CPUMIPSTLBContext::map_address() handlers scopePhilippe Mathieu-Daudé
The 3 map_address() handlers are local to tlb_helper.c, no need to have their prototype declared publically. Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Message-Id: <20210428170410.479308-23-f4bug@amsat.org>
2021-05-02target/mips: Move tlb_helper.c to tcg/sysemu/Philippe Mathieu-Daudé
Move tlb_helper.c to the tcg/sysemu/ subdir, along with the following 3 declarations to tcg-internal.h: - cpu_mips_tlb_flush() - cpu_mips_translate_address() - r4k_invalidate_tlb() Simplify tlb_helper.c #ifdef'ry because files in tcg/sysemu/ are only build when sysemu mode is configured.

mmu_init() is only required by TCG accelerator. Restrict its declaration and call to TCG. Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Message-Id: <20210428170410.479308-21-f4bug@amsat.org>
2021-05-02target/mips: Move sysemu TCG-specific code to tcg/sysemu/ subfolderPhilippe Mathieu-Daudé
Move cp0_helper.c and mips-semi.c to the new tcg/sysemu/ folder, adapting the Meson machinery. Move the opcode definitions to tcg/sysemu_helper.h.inc.

2021-05-02target/mips: Add simple user-mode mips_cpu_tlb_fill()Philippe Mathieu-Daudé
tlb_helper.c's #ifdef'ry hides a quite simple user-mode implementation of mips_cpu_tlb_fill(). Copy the user-mode implementation (without #ifdef'ry) to tcg/user/helper.c and simplify tlb_helper.c's #ifdef'ry. This will allow us to restrict tlb_helper.c to sysemu.

2021-05-02target/mips: Add simple user-mode mips_cpu_do_interrupt()Philippe Mathieu-Daudé
The #ifdef'ry hides that the user-mode implementation of mips_cpu_do_interrupt() simply sets exception_index = EXCP_NONE. Add this simple implementation to tcg/user/tlb_helper.c, and the corresponding Meson machinery to build this file when user emulation is configured.
