From 86f004bdfcc1c14ace99f5fccf540c0d813d2254 Mon Sep 17 00:00:00 2001 From: Marek Olšák Date: Fri, 5 Oct 2018 18:09:37 -0400 Subject: radeonsi: optimize and allow reg > 31 in radeon_opt_set_context_reg functions reg_saved will have 64 bits, and (1 << reg) where reg > 31 has undefined behavior. (1ull << reg) would be correct for 64 bits. This commit shifts the other way in order to merge the conditions. --- src/gallium/drivers/radeonsi/si_build_pm4.h | 34 ++++++++++------------------- 1 file changed, 12 insertions(+), 22 deletions(-) (limited to 'src/gallium/drivers') diff --git a/src/gallium/drivers/radeonsi/si_build_pm4.h b/src/gallium/drivers/radeonsi/si_build_pm4.h index f10929a67f9..796adda0963 100644 --- a/src/gallium/drivers/radeonsi/si_build_pm4.h +++ b/src/gallium/drivers/radeonsi/si_build_pm4.h @@ -116,12 +116,11 @@ static inline void radeon_opt_set_context_reg(struct si_context *sctx, unsigned { struct radeon_cmdbuf *cs = sctx->gfx_cs; - if (!(sctx->tracked_regs.reg_saved & (1 << reg)) || - sctx->tracked_regs.reg_value[reg] != value ) { - + if (((sctx->tracked_regs.reg_saved >> reg) & 0x1) != 0x1 || + sctx->tracked_regs.reg_value[reg] != value) { radeon_set_context_reg(cs, offset, value); - sctx->tracked_regs.reg_saved |= 1 << reg; + sctx->tracked_regs.reg_saved |= 0x1ull << reg; sctx->tracked_regs.reg_value[reg] = value; } } @@ -138,18 +137,16 @@ static inline void radeon_opt_set_context_reg2(struct si_context *sctx, unsigned { struct radeon_cmdbuf *cs = sctx->gfx_cs; - if (!(sctx->tracked_regs.reg_saved & (1 << reg)) || - !(sctx->tracked_regs.reg_saved & (1 << (reg + 1))) || + if (((sctx->tracked_regs.reg_saved >> reg) & 0x3) != 0x3 || sctx->tracked_regs.reg_value[reg] != value1 || - sctx->tracked_regs.reg_value[reg+1] != value2 ) { - + sctx->tracked_regs.reg_value[reg+1] != value2) { radeon_set_context_reg_seq(cs, offset, 2); radeon_emit(cs, value1); radeon_emit(cs, value2); sctx->tracked_regs.reg_value[reg] = value1; sctx->tracked_regs.reg_value[reg+1] = value2; - sctx->tracked_regs.reg_saved |= 3 << reg; + sctx->tracked_regs.reg_saved |= 0x3ull << reg; } } @@ -162,13 +159,10 @@ static inline void radeon_opt_set_context_reg3(struct si_context *sctx, unsigned { struct radeon_cmdbuf *cs = sctx->gfx_cs; - if (!(sctx->tracked_regs.reg_saved & (1 << reg)) || - !(sctx->tracked_regs.reg_saved & (1 << (reg + 1))) || - !(sctx->tracked_regs.reg_saved & (1 << (reg + 2))) || + if (((sctx->tracked_regs.reg_saved >> reg) & 0x7) != 0x7 || sctx->tracked_regs.reg_value[reg] != value1 || sctx->tracked_regs.reg_value[reg+1] != value2 || - sctx->tracked_regs.reg_value[reg+2] != value3 ) { - + sctx->tracked_regs.reg_value[reg+2] != value3) { radeon_set_context_reg_seq(cs, offset, 3); radeon_emit(cs, value1); radeon_emit(cs, value2); @@ -177,7 +171,7 @@ static inline void radeon_opt_set_context_reg3(struct si_context *sctx, unsigned sctx->tracked_regs.reg_value[reg] = value1; sctx->tracked_regs.reg_value[reg+1] = value2; sctx->tracked_regs.reg_value[reg+2] = value3; - sctx->tracked_regs.reg_saved |= 7 << reg; + sctx->tracked_regs.reg_saved |= 0x7ull << reg; } } @@ -191,15 +185,11 @@ static inline void radeon_opt_set_context_reg4(struct si_context *sctx, unsigned { struct radeon_cmdbuf *cs = sctx->gfx_cs; - if (!(sctx->tracked_regs.reg_saved & (1 << reg)) || - !(sctx->tracked_regs.reg_saved & (1 << (reg + 1))) || - !(sctx->tracked_regs.reg_saved & (1 << (reg + 2))) || - !(sctx->tracked_regs.reg_saved & (1 << (reg + 3))) || + if (((sctx->tracked_regs.reg_saved >> reg) & 0xf) != 0xf || sctx->tracked_regs.reg_value[reg] != value1 || sctx->tracked_regs.reg_value[reg+1] != value2 || sctx->tracked_regs.reg_value[reg+2] != value3 || - sctx->tracked_regs.reg_value[reg+3] != value4 ) { - + sctx->tracked_regs.reg_value[reg+3] != value4) { radeon_set_context_reg_seq(cs, offset, 4); radeon_emit(cs, value1); radeon_emit(cs, value2); @@ -210,7 +200,7 @@ static inline void radeon_opt_set_context_reg4(struct si_context *sctx, unsigned sctx->tracked_regs.reg_value[reg+1] = value2; sctx->tracked_regs.reg_value[reg+2] = value3; sctx->tracked_regs.reg_value[reg+3] = value4; - sctx->tracked_regs.reg_saved |= 0xf << reg; + sctx->tracked_regs.reg_saved |= 0xfull << reg; } } -- cgit v1.2.3
