2021-05-04hw/sparc: Allow building without the leon3 machinePhilippe Mathieu-Daudé
When building without the leon3 machine, we get this link failure: /usr/bin/ld: target_sparc_int32_helper.c.o: in function `leon3_irq_manager': target/sparc/int32_helper.c:172: undefined reference to `leon3_irq_ack' This is because the leon3_irq_ack() is declared in hw/sparc/leon3.c, which is only build when CONFIG_LEON3 is selected. Fix by moving the leon3_cache_control_int() / leon3_irq_manager() (which are specific to the leon3 machine) to hw/sparc/leon3.c. Move the trace events along (but don't rename them). leon3_irq_ack() is now locally used, declare it static to reduce its scope.

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.

To avoid callers to emit dead code if check_cp0_enabled() raise an exception, let it return a boolean value, whether CP0 is enabled or not.
