From dc302c00611b6973fbc55e9fdd643ad24c370bd1 Mon Sep 17 00:00:00 2001 From: Peter Bergner Date: Thu, 4 Jun 2015 20:27:03 -0500 Subject: [PATCH] Add hwsync extended mnemonic. This commit adds a new extended menmonic for "sync 0" (same as "sync"). The ISA documentation doesn't explicitly mention hwsync as an extended mnemonic (yet), but it does mention "heavyweight sync" and "hwsync" as the operation that gets performed when the sync's L field is 0. This is only enabled for POWER4 and later. opcodes/ * ppc-opc.c: (powerpc_opcodes) : New extended mnemonic. gas/testsuite/ * gas/ppc/a2.d: Fixup test case due to new extended mnemonic. * gas/ppc/power4.s : Add tests. * gas/ppc/power4.d: Likewise. --- gas/testsuite/gas/ppc/a2.d | 6 +++--- gas/testsuite/gas/ppc/power4.d | 9 ++++++++- gas/testsuite/gas/ppc/power4.s | 7 +++++++ opcodes/ppc-opc.c | 1 + 4 files changed, 19 insertions(+), 4 deletions(-) diff --git a/gas/testsuite/gas/ppc/a2.d b/gas/testsuite/gas/ppc/a2.d index 700c665..aa05cbc 100644 --- a/gas/testsuite/gas/ppc/a2.d +++ b/gas/testsuite/gas/ppc/a2.d @@ -544,9 +544,9 @@ Disassembly of section \.text: 810: (7e 95 01 90|90 01 95 7e) subfze r20,r21 814: (7e 95 05 91|91 05 95 7e) subfzeo\. r20,r21 818: (7e 95 05 90|90 05 95 7e) subfzeo r20,r21 - 81c: (7c 00 04 ac|ac 04 00 7c) sync - 820: (7c 00 04 ac|ac 04 00 7c) sync - 824: (7c 00 04 ac|ac 04 00 7c) sync + 81c: (7c 00 04 ac|ac 04 00 7c) hwsync + 820: (7c 00 04 ac|ac 04 00 7c) hwsync + 824: (7c 00 04 ac|ac 04 00 7c) hwsync 828: (7c 20 04 ac|ac 04 20 7c) lwsync 82c: (7c aa 58 88|88 58 aa 7c) tdlge r10,r11 830: (08 aa 00 64|64 00 aa 08) tdlgei r10,100 diff --git a/gas/testsuite/gas/ppc/power4.d b/gas/testsuite/gas/ppc/power4.d index cd71245..8a09c05 100644 --- a/gas/testsuite/gas/ppc/power4.d +++ b/gas/testsuite/gas/ppc/power4.d @@ -10,7 +10,7 @@ start address 0x0+ Sections: Idx Name +Size +VMA +LMA +File off +Algn - +0 \.text +0+cc +0+ +0+ +.* + +0 \.text +0+e8 +0+ +0+ +.* +CONTENTS, ALLOC, LOAD, RELOC, READONLY, CODE +1 \.data +0+20 +0+ +0+ +.* +CONTENTS, ALLOC, LOAD, DATA @@ -99,3 +99,10 @@ Disassembly of section \.text: .*: (f8 05 00 12|12 00 05 f8) stq r0,16\(r5\) .*: (f8 45 00 12|12 00 45 f8) stq r2,16\(r5\) .*: (7c 00 03 e4|e4 03 00 7c) slbia +.*: (7c 00 04 ac|ac 04 00 7c) hwsync +.*: (7c 00 04 ac|ac 04 00 7c) hwsync +.*: (7c 00 04 ac|ac 04 00 7c) hwsync +.*: (7c 20 04 ac|ac 04 20 7c) lwsync +.*: (7c 20 04 ac|ac 04 20 7c) lwsync +.*: (7c 40 04 ac|ac 04 40 7c) ptesync +.*: (7c 40 04 ac|ac 04 40 7c) ptesync diff --git a/gas/testsuite/gas/ppc/power4.s b/gas/testsuite/gas/ppc/power4.s index 49423a1..583284c 100644 --- a/gas/testsuite/gas/ppc/power4.s +++ b/gas/testsuite/gas/ppc/power4.s @@ -72,6 +72,13 @@ dsym1: stq 0,16(5) stq 2,16(5) slbia + hwsync + sync + sync 0 + lwsync + sync 1 + ptesync + sync 2 .section ".data" usym0: .llong 0xcafebabe diff --git a/opcodes/ppc-opc.c b/opcodes/ppc-opc.c index 57a0973..8f0ee04 100644 --- a/opcodes/ppc-opc.c +++ b/opcodes/ppc-opc.c @@ -5465,6 +5465,7 @@ const struct powerpc_opcode powerpc_opcodes[] = { {"lswi", X(31,597), X_MASK, PPCCOM|PPCVLE, E500|E500MC, {RT, RAX, NBI}}, {"lsi", X(31,597), X_MASK, PWRCOM, PPCNONE, {RT, RA0, NB}}, +{"hwsync", XSYNC(31,598,0), 0xffffffff, POWER4, BOOKE|PPC476, {0}}, {"lwsync", XSYNC(31,598,1), 0xffffffff, PPC, E500, {0}}, {"ptesync", XSYNC(31,598,2), 0xffffffff, PPC64, PPCNONE, {0}}, {"sync", X(31,598), XSYNCLE_MASK,E6500, PPCNONE, {LS, ESYNC}}, -- 2.7.4
