tcg_reg_alloc_op() allocates arrays of TCG_MAX_OP_ARGS elements. The Aarch64 target already does this since commit 8d8db193f25 ("tcg-aarch64: Hoist common argument loads in tcg_out_op"), SPARC since commit b357f902bff ("tcg-sparc: Hoist common argument loads in tcg_out_op").
RISCV missed it upon introduction in commit bdf503819ee ("tcg/riscv: Add the out op decoder"), MIPS since commit 22ee3a987d5 ("tcg-mips: Hoist args loads") and i386 since commit 42d5b514928 ("tcg/i386: Hoist common arguments in tcg_out_op"). Provide this information as a hint to the compiler in the function prototype, and update the funtion definitions. This fixes this warning (using GCC 11): tcg/aarch64/tcg-target.c.inc:1855:37: error: argument 3 of type 'const TCGArg[16]' {aka 'const long unsigned int[16]'} with mismatched bound [-Werror=array-parameter=] tcg/aarch64/tcg-target.c.inc:1856:34: error: argument 4 of type 'const int[16]' with mismatched bound [-Werror=array-parameter=] Reported-by: Miroslav Rezanina <mreza...@redhat.com> Reviewed-by: Miroslav Rezanina <mreza...@redhat.com> Reviewed-by: Richard Henderson <richard.hender...@linaro.org> Signed-off-by: Philippe Mathieu-Daudé <f4...@amsat.org> --- tcg/tcg.c | 5 +++-- tcg/i386/tcg-target.c.inc | 3 ++- tcg/mips/tcg-target.c.inc | 3 ++- tcg/riscv/tcg-target.c.inc | 3 ++- tcg/tci/tcg-target.c.inc | 5 +++-- 5 files changed, 12 insertions(+), 7 deletions(-) diff --git a/tcg/tcg.c b/tcg/tcg.c index 472bf1755bf..97d074d8fab 100644 --- a/tcg/tcg.c +++ b/tcg/tcg.c @@ -110,8 +110,9 @@ static void tcg_out_ld(TCGContext *s, TCGType type, TCGReg ret, TCGReg arg1, static bool tcg_out_mov(TCGContext *s, TCGType type, TCGReg ret, TCGReg arg); static void tcg_out_movi(TCGContext *s, TCGType type, TCGReg ret, tcg_target_long arg); -static void tcg_out_op(TCGContext *s, TCGOpcode opc, const TCGArg *args, - const int *const_args); +static void tcg_out_op(TCGContext *s, TCGOpcode opc, + const TCGArg args[TCG_MAX_OP_ARGS], + const int const_args[TCG_MAX_OP_ARGS]); #if TCG_TARGET_MAYBE_vec static bool tcg_out_dup_vec(TCGContext *s, TCGType type, unsigned vece, TCGReg dst, TCGReg src); diff --git a/tcg/i386/tcg-target.c.inc b/tcg/i386/tcg-target.c.inc index 46e856f4421..d121dca8789 100644 --- a/tcg/i386/tcg-target.c.inc +++ b/tcg/i386/tcg-target.c.inc @@ -2215,7 +2215,8 @@ static void tcg_out_qemu_st(TCGContext *s, const TCGArg *args, bool is64) } static inline void tcg_out_op(TCGContext *s, TCGOpcode opc, - const TCGArg *args, const int *const_args) + const TCGArg args[TCG_MAX_OP_ARGS], + const int const_args[TCG_MAX_OP_ARGS]) { TCGArg a0, a1, a2; int c, const_a2, vexop, rexw = 0; diff --git a/tcg/mips/tcg-target.c.inc b/tcg/mips/tcg-target.c.inc index add157f6c32..b9bb54f0ecc 100644 --- a/tcg/mips/tcg-target.c.inc +++ b/tcg/mips/tcg-target.c.inc @@ -1691,7 +1691,8 @@ static void tcg_out_clz(TCGContext *s, MIPSInsn opcv2, MIPSInsn opcv6, } static inline void tcg_out_op(TCGContext *s, TCGOpcode opc, - const TCGArg *args, const int *const_args) + const TCGArg args[TCG_MAX_OP_ARGS], + const int const_args[TCG_MAX_OP_ARGS]) { MIPSInsn i1, i2; TCGArg a0, a1, a2; diff --git a/tcg/riscv/tcg-target.c.inc b/tcg/riscv/tcg-target.c.inc index c60b91ba58f..5bf0d069532 100644 --- a/tcg/riscv/tcg-target.c.inc +++ b/tcg/riscv/tcg-target.c.inc @@ -1238,7 +1238,8 @@ static void tcg_out_qemu_st(TCGContext *s, const TCGArg *args, bool is_64) static const tcg_insn_unit *tb_ret_addr; static void tcg_out_op(TCGContext *s, TCGOpcode opc, - const TCGArg *args, const int *const_args) + const TCGArg args[TCG_MAX_OP_ARGS], + const int const_args[TCG_MAX_OP_ARGS]) { TCGArg a0 = args[0]; TCGArg a1 = args[1]; diff --git a/tcg/tci/tcg-target.c.inc b/tcg/tci/tcg-target.c.inc index d5a4d9d37cf..60464524f3d 100644 --- a/tcg/tci/tcg-target.c.inc +++ b/tcg/tci/tcg-target.c.inc @@ -553,8 +553,9 @@ static inline void tcg_out_call(TCGContext *s, const tcg_insn_unit *arg) old_code_ptr[1] = s->code_ptr - old_code_ptr; } -static void tcg_out_op(TCGContext *s, TCGOpcode opc, const TCGArg *args, - const int *const_args) +static void tcg_out_op(TCGContext *s, TCGOpcode opc, + const TCGArg args[TCG_MAX_OP_ARGS], + const int const_args[TCG_MAX_OP_ARGS]) { uint8_t *old_code_ptr = s->code_ptr; -- 2.26.2
