2023-12-31meson: rename config_allPaolo Bonzini
config_all now lists only accelerators, rename it to indicate its actual content. Reviewed-by: Philippe Mathieu-Daudé <philmd@linaro.org> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2023-10-07meson: Rename target_softmmu_arch -> target_system_archPhilippe Mathieu-Daudé
Finish the convertion started with commit de6cd7599b ("meson: Replace softmmu_ss -> system_ss"). If the $target_type is 'system', then use the target_system_arch[] source set :) Mechanical change doing: $ sed -i -e s/target_softmmu_arch/target_system_arch/g \ $(git grep -l target_softmmu_arch) Signed-off-by: Philippe Mathieu-Daudé <philmd@linaro.org> Message-ID: <20231004090629.37473-13-philmd@linaro.org> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2023-06-20meson: Replace softmmu_ss -> system_ssPhilippe Mathieu-Daudé
We use the user_ss[] array to hold the user emulation sources, and the softmmu_ss[] array to hold the system emulation ones. Hold the latter in the 'system_ss[]' array for parity with user emulation.

2021-05-02target/mips: Move TCG source files under tcg/ sub directoryPhilippe Mathieu-Daudé
To ease maintenance, move all TCG specific files under the tcg/ sub-directory. Adapt the Meson machinery. The following prototypes: - mips_tcg_init() - mips_cpu_do_unaligned_access() - mips_cpu_do_transaction_failed() can now be restricted to the "tcg-internal.h" header.

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.

2021-05-02target/mips: Move msa_reset() to new source filePhilippe Mathieu-Daudé
mips_cpu_reset() is used by all accelerators, and calls msa_reset(), which is defined in msa_helper.c. Beside msa_reset(), the rest of msa_helper.c is only useful to the TCG accelerator. To be able to restrict this helper file to TCG, we need to move msa_reset() out of it.

2021-05-02target/mips: Move IEEE rounding mode array to new source filePhilippe Mathieu-Daudé
restore_msa_fp_status() is declared inlined in fpu_helper.h, and uses the ieee_rm[] array. Therefore any code calling restore_msa_fp_status() must have access to this ieee_rm[] array. kvm_mips_get_fpu_registers(), which is in target/mips/kvm.c, calls restore_msa_fp_status. Except this tiny array, the rest of fpu_helper.c is only useful for the TCG accelerator. To be able to restrict fpu_helper.c to TCG, we need to move the ieee_rm[] array to a new source file.

Introduce decodetree structure to decode the tx79 opcodes. Start it by moving the existing MFHI1 and MFLO1 opcodes. Remove unnecessary comments. As the TX79 share opcodes with the TX19/TX39/TX49 CPUs, we introduce the decode_ext_txx9() dispatcher where we will add the other decoders later.
