JR opcode (Jump Register) only takes 1 argument, $rs. JALR (Jump And Link Register) takes 3: $rs, $rd and $hint.

Per JR encoding, both $rd and $hint ('sa') are decoded as zero. Later this code got extracted to decode_opc_special(), commit 7a387fffce5 used definitions instead of magic values: case OPC_JR ... OPC_JALR: gen_compute_branch(ctx, op1, rs, rd, sa); Finally commit 0aefa33318b moved OPC_JR out of decode_opc_special, to a new 'decode_opc_special_legacy' function: @@ -15851,6 +15851,9 @@ static void decode_opc_special_legacy(CPUMIPSState *env, DisasContext *ctx) + case OPC_JR: + gen_compute_branch(ctx, op1, 4, rs, rd, sa); + break; @@ -15933,7 +15936,7 @@ static void decode_opc_special(CPUMIPSState *env, DisasContext *ctx) - case OPC_JR ...

2021-07-09tcg: Avoid including 'trace-tcg.h' in target translate.cPhilippe Mathieu-Daudé1-1/+0
The root trace-events only declares a single TCG event: $ git grep -w tcg trace-events trace-events:115:# tcg/tcg-op.c trace-events:137:vcpu tcg guest_mem_before(TCGv vaddr, uint16_t info) "info=%d", "vaddr=0x%016"PRIx64" info=%d" and only a tcg/tcg-op.c uses it: $ git grep -l trace_guest_mem_before_tcg tcg/tcg-op.c therefore it is pointless to include "trace-tcg.h" in each target (because it is not used). Remove it. Signed-off-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Message-Id: <20210629050935.2570721-1-f4bug@amsat.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2021-07-09meson: Introduce target-specific KconfigPhilippe Mathieu-Daudé1-0/+6
Add a target-specific Kconfig. We need the definitions in Kconfig so the minikconf tool can verify they exits. However CONFIG_FOO is only enabled for target foo via the meson.build rules. Two architecture have a particularity, ARM and MIPS. As their translators have been split you can potentially build a plain 32 bit build along with a 64-bit version including the 32-bit subset.
