Signed-off-by: Peter Maydell --- Do we want to define a QEMU_UNUSED macro in compiler.h? We don't seem to have done for the existing uses of this attribute in tree. tcg/tcg.c | 20 ++++++++++++-------- 1 file changed, 12 insertions(+), 8 deletions(-) diff --git a/tcg/tcg.c b/tcg/tcg.c index 2c5732d..fe55d05 100644 --- a/tcg/tcg.c +++ b/tcg/tcg.c @@ -125,19 +125,20 @@ static TCGRegSet tcg_target_available_regs[2]; static TCGRegSet tcg_target_call_clobber_regs; #if TCG_TARGET_INSN_UNIT_SIZE == 1 -static inline void tcg_out8(TCGContext *s, uint8_t v) +static __attribute__((unused)) inline void tcg_out8(TCGContext *s, uint8_t v) { *s->code_ptr++ = v; } -static inline void tcg_patch8(tcg_insn_unit *p, uint8_t v) +static __attribute__((unused)) inline void tcg_patch8(tcg_insn_unit *p, + uint8_t v) { *p = v; } #endif #if TCG_TARGET_INSN_UNIT_SIZE <= 2 -static inline void tcg_out16(TCGContext *s, uint16_t v) +static __attribute__((unused)) inline void tcg_out16(TCGContext *s, uint16_t v) { if (TCG_TARGET_INSN_UNIT_SIZE == 2) { *s->code_ptr++ = v; @@ -148,7 +149,8 @@ static inline void tcg_out16(TCGContext *s, uint16_t v) } } -static inline void tcg_patch16(tcg_insn_unit *p, uint16_t v) +static __attribute__((unused)) inline void tcg_patch16(tcg_insn_unit *p, + uint16_t v) { if (TCG_TARGET_INSN_UNIT_SIZE == 2) { *p = v; @@ -159,7 +161,7 @@ static inline void tcg_patch16(tcg_insn_unit *p, uint16_t v) #endif #if TCG_TARGET_INSN_UNIT_SIZE <= 4 -static inline void tcg_out32(TCGContext *s, uint32_t v) +static __attribute__((unused)) inline void tcg_out32(TCGContext *s, uint32_t v) { if (TCG_TARGET_INSN_UNIT_SIZE == 4) { *s->code_ptr++ = v; @@ -170,7 +172,8 @@ static inline void tcg_out32(TCGContext *s, uint32_t v) } } -static inline void tcg_patch32(tcg_insn_unit *p, uint32_t v) +static __attribute__((unused)) inline void tcg_patch32(tcg_insn_unit *p, + uint32_t v) { if (TCG_TARGET_INSN_UNIT_SIZE == 4) { *p = v; @@ -181,7 +184,7 @@ static inline void tcg_patch32(tcg_insn_unit *p, uint32_t v) #endif #if TCG_TARGET_INSN_UNIT_SIZE <= 8 -static inline void tcg_out64(TCGContext *s, uint64_t v) +static __attribute__((unused)) inline void tcg_out64(TCGContext *s, uint64_t v) { if (TCG_TARGET_INSN_UNIT_SIZE == 8) { *s->code_ptr++ = v; @@ -192,7 +195,8 @@ static inline void tcg_out64(TCGContext *s, uint64_t v) } } -static inline void tcg_patch64(tcg_insn_unit *p, uint64_t v) +static __attribute__((unused)) inline void tcg_patch64(tcg_insn_unit *p, + uint64_t v) { if (TCG_TARGET_INSN_UNIT_SIZE == 8) { *p = v; -- 1.8.5.4
