[PULL 2/2] target/hexagon: fix some occurrences of -Wshadow=local
Of the changes in this commit, the changes in `HELPER(commit_hvx_stores)()` are less obvious. They are required because of some macro invocations like SCATTER_OP_WRITE_TO_MEM(). e.g.: In file included from ../target/hexagon/op_helper.c:31: ../target/hexagon/mmvec/macros.h:205:18: error: declaration of ‘i’ shadows a previous local [-Werror=shadow=compatible-local] 205 | for (int i = 0; i < sizeof(MMVector); i += sizeof(TYPE)) { \ | ^ ../target/hexagon/op_helper.c:157:17: note: in expansion of macro ‘SCATTER_OP_WRITE_TO_MEM’ 157 | SCATTER_OP_WRITE_TO_MEM(uint16_t); | ^~~ ../target/hexagon/op_helper.c:135:9: note: shadowed declaration is here 135 | int i; | ^ In file included from ../target/hexagon/op_helper.c:31: ../target/hexagon/mmvec/macros.h:204:19: error: declaration of ‘ra’ shadows a previous local [-Werror=shadow=compatible-local] 204 | uintptr_t ra = GETPC(); \ | ^~ ../target/hexagon/op_helper.c:160:17: note: in expansion of macro ‘SCATTER_OP_WRITE_TO_MEM’ 160 | SCATTER_OP_WRITE_TO_MEM(uint32_t); | ^~~ ../target/hexagon/op_helper.c:134:15: note: shadowed declaration is here 134 | uintptr_t ra = GETPC(); | ^~ Reviewed-by: Matheus Tavares Bernardino Signed-off-by: Brian Cain Reviewed-by: Philippe Mathieu-Daudé Message-Id: <20231008220945.983643-3-bc...@quicinc.com> --- target/hexagon/imported/alu.idef | 6 +++--- target/hexagon/mmvec/macros.h| 2 +- target/hexagon/op_helper.c | 9 +++-- target/hexagon/translate.c | 10 +- 4 files changed, 12 insertions(+), 15 deletions(-) diff --git a/target/hexagon/imported/alu.idef b/target/hexagon/imported/alu.idef index 12d2aac5d4..b855676989 100644 --- a/target/hexagon/imported/alu.idef +++ b/target/hexagon/imported/alu.idef @@ -1142,9 +1142,9 @@ Q6INSN(A4_cround_rr,"Rd32=cround(Rs32,Rt32)",ATTRIBS(),"Convergent Round", {RdV tmp128 = fSHIFTR128(tmp128, SHIFT);\ DST = fCAST16S_8S(tmp128);\ } else {\ -size16s_t rndbit_128 = fCAST8S_16S((1LL << (SHIFT - 1))); \ -size16s_t src_128 = fCAST8S_16S(SRC); \ -size16s_t tmp128 = fADD128(src_128, rndbit_128);\ +rndbit_128 = fCAST8S_16S((1LL << (SHIFT - 1))); \ +src_128 = fCAST8S_16S(SRC); \ +tmp128 = fADD128(src_128, rndbit_128);\ tmp128 = fSHIFTR128(tmp128, SHIFT);\ DST = fCAST16S_8S(tmp128);\ } diff --git a/target/hexagon/mmvec/macros.h b/target/hexagon/mmvec/macros.h index a655634fd1..1ceb9453ee 100644 --- a/target/hexagon/mmvec/macros.h +++ b/target/hexagon/mmvec/macros.h @@ -201,7 +201,7 @@ } while (0) #define SCATTER_OP_WRITE_TO_MEM(TYPE) \ do { \ -uintptr_t ra = GETPC(); \ +ra = GETPC(); \ for (int i = 0; i < sizeof(MMVector); i += sizeof(TYPE)) { \ if (test_bit(i, env->vtcm_log.mask)) { \ TYPE dst = 0; \ diff --git a/target/hexagon/op_helper.c b/target/hexagon/op_helper.c index 8ca3976a65..da10ac5847 100644 --- a/target/hexagon/op_helper.c +++ b/target/hexagon/op_helper.c @@ -132,10 +132,9 @@ void HELPER(gather_store)(CPUHexagonState *env, uint32_t addr, int slot) void HELPER(commit_hvx_stores)(CPUHexagonState *env) { uintptr_t ra = GETPC(); -int i; /* Normal (possibly masked) vector store */ -for (i = 0; i < VSTORES_MAX; i++) { +for (int i = 0; i < VSTORES_MAX; i++) { if (env->vstore_pending[i]) { env->vstore_pending[i] = 0; target_ulong va = env->vstore[i].va; @@ -162,7 +161,7 @@ void HELPER(commit_hvx_stores)(CPUHexagonState *env) g_assert_not_reached(); } } else { -for (i = 0; i < sizeof(MMVector); i++) { +for (int i = 0; i < sizeof(MMVector); i++) { if (test_bit(i, env->vtcm_log.mask)) { cpu_stb_data_ra(env, env->vtcm_log.va[i], env->vtcm_log.data.ub[i], ra); @@ -505,10 +504,8 @@ void HELPER(probe_pkt_scalar_store_s0)(CPUHexagonState *env, int args) static void probe_hvx_stores(CPUHexagonState *env, int mmu_idx, uintptr_t retaddr) { -int i; - /* Normal (possibly masked) vector store */ -for (i = 0; i < VSTORES_MAX; i++) { +for (int i = 0; i < VSTORES_MAX; i++) { if (env->vstore_pending[i]) { target_ulong va = env->vstore[i].va; int size = env->vstore[i].size; diff --git a/target/hexagon/translate.c b/target/hexagon/translate.c index 663b7bbc3a..666c061180 100644 --- a/target/hexagon/translate.c +++ b/target/hexagon/translate.c @@ -553,7 +553,7 @@ static void gen_sta
