Christophe Leroy 22e9c88d48 powerpc/64: reuse PPC32 static inline flush_dcache_range() ... This patch drops the assembly PPC64 version of flush_dcache_range() and re-uses the PPC32 static inline version. With GCC 8.1, the following code is generated: void flush_test(unsigned long start, unsigned long stop) { flush_dcache_range(start, stop); } 0000000000000130 <.flush_test>: 130: 3d 22 00 00 addis r9,r2,0 132: R_PPC64_TOC16_HA .data+0x8 134: 81 09 00 00 lwz r8,0(r9) 136: R_PPC64_TOC16_LO .data+0x8 138: 3d 22 00 00 addis r9,r2,0 13a: R_PPC64_TOC16_HA .data+0xc 13c: 80 e9 00 00 lwz r7,0(r9) 13e: R_PPC64_TOC16_LO .data+0xc 140: 7d 48 00 d0 neg r10,r8 144: 7d 43 18 38 and r3,r10,r3 148: 7c 00 04 ac hwsync 14c: 4c 00 01 2c isync 150: 39 28 ff ff addi r9,r8,-1 154: 7c 89 22 14 add r4,r9,r4 158: 7c 83 20 50 subf r4,r3,r4 15c: 7c 89 3c 37 srd. r9,r4,r7 160: 41 82 00 1c beq 17c <.flush_test+0x4c> 164: 7d 29 03 a6 mtctr r9 168: 60 00 00 00 nop 16c: 60 00 00 00 nop 170: 7c 00 18 ac dcbf 0,r3 174: 7c 63 42 14 add r3,r3,r8 178: 42 00 ff f8 bdnz 170 <.flush_test+0x40> 17c: 7c 00 04 ac hwsync 180: 4c 00 01 2c isync 184: 4e 80 00 20 blr 188: 60 00 00 00 nop 18c: 60 00 00 00 nop Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>		2019-07-05 02:06:37 +10:00
