From 7ecc513a44095d614f10e89c67d9be5826abacf9 Mon Sep 17 00:00:00 2001 From: Dominik Vogt Date: Tue, 29 Sep 2015 13:22:07 +0100 Subject: Add support for extensions in the .machine pseudoop on S/390, e.g. ".machine zEC12+nohtm+vx" gas * doc/c-s390.texi: Add documentation. Add missing code markup. * config/tc-s390.c (current_flags): New static variable. (s390_parse_cpu): Parse cpu flags a la "+nohtm" etc. (s390_setup_opcodes): Use cpu flags to determine the set of opcodes. Fix indentation. (md_parse_option): Call s390_parse_cpu with the new signature. (s390_machine): Likewise. Keep track of current_flags. Simplify code a bit. undefine MAX_HISTORY at end of function. (s390_machinemode): undefine MAX_HISTORY at end of function. Update an error message. tests * gas/s390/s390.exp: Add new tests. * gas/s390/machine-parsing-1.s: New test file. * gas/s390/machine-parsing-1.l: Likewise. * gas/s390/machine-parsing-2.s: Likewise. * gas/s390/machine-parsing-2.l: Likewise. * gas/s390/machine-parsing-3.s: Likewise. * gas/s390/machine-parsing-3.l: Likewise. * gas/s390/machine-parsing-4.s: Likewise. * gas/s390/machine-parsing-4.l: Likewise. * gas/s390/machine-parsing-5.s: Likewise. * gas/s390/machine-parsing-5.l: Likewise. * gas/s390/machine-parsing-6.s: Likewise. * gas/s390/machine-parsing-6.l: Likewise. opcode * s390.h (S390_INSTR_FLAG_HTM): New flag. (S390_INSTR_FLAG_VX): New flag. (S390_INSTR_FLAG_FACILITY_MASK): New flag mask. opcodes * s390-mkopc.c (main): Parse htm and vx flag. * s390-opc.txt: Mark instructions from the hardware transactional memory and vector facilities with the "htm"/"vx" flag. --- gas/ChangeLog | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) (limited to 'gas/ChangeLog') diff --git a/gas/ChangeLog b/gas/ChangeLog index af99b96..5420973 100644 --- a/gas/ChangeLog +++ b/gas/ChangeLog @@ -1,3 +1,19 @@ +2015-09-29 Dominik Vogt + + * doc/c-s390.texi: Add documentation. + Add missing code markup. + * config/tc-s390.c (current_flags): New static variable. + (s390_parse_cpu): Parse cpu flags a la "+nohtm" etc. + (s390_setup_opcodes): Use cpu flags to determine the set of opcodes. + Fix indentation. + (md_parse_option): Call s390_parse_cpu with the new signature. + (s390_machine): Likewise. + Keep track of current_flags. + Simplify code a bit. + undefine MAX_HISTORY at end of function. + (s390_machinemode): undefine MAX_HISTORY at end of function. + Update an error message. + 2015-08-11 Peter Zotov PR ld/18759 -- cgit v1.1
