The optimizer now juggles around the base and index register if that opens
up the possibility of folding the shift into the instruction.
This can only be done in the case of addressmode=AM_OFFSET, in case of
[AM_POSTINDEXED, AM_PREINDEXED] we can not move the base register, as this
would cause havoc and destruction.
git-svn-id: trunk@24645 -
- removed mips_cpu variable and cpu_mips_default CPU type.
* globals.pas: default CPU type changed to MIPS2, this is what was passed to assembler before.
git-svn-id: trunk@24643 -
- references cannot be in brackets
- registers are only prefixed by dollar, never by percent
- syntax x@LO is not supported, must be %lo(x).
git-svn-id: trunk@24633 -
* reworked condition codes, changed BC1T and BC1F from separate instructions to condition jumps.
- removed A_P_SW, A_P_LW and A_SPARC8UNIMP
+ support '.set at' and '.set noat' directives
+ prepare to support bgtz,bgez,bltz,blez instructions.
git-svn-id: trunk@24631 -
symsym.pas:
- remove "tgenericconstraintdata" and any using/loading/writing of it in "ttypesym"
- remove "tgenericconstraintflag"
symdef.pas:
+ add "tgenericconstraintdata"
+ load and write "genconstraintdata" in "tstoreddef"
symconst.pas:
+ add "tgenericconstraintflag" so it can be used in "ppudump" as well
defcmp.pas, compare_defs_ext:
* as we allow global operator overloads we can't really determine whether two defs are compatible, because a valid operator for the specialization types might just happen to be in scope of the generic; so for now constraints are only strictly checked when declaring a specialization
pgenutil.pas:
* adjust "parse_generic_parameters" and "check_generic_constraints" to the new location of the constraint data
ppudump.pp:
* corrrectly parse defs which contain generic constraints
git-svn-id: trunk@24628 -
symdef.pas, tstoreddef:
+ comment that the list is allocated on demand (and thus should be checked for Nil)
+ fillgenericparas: create the list when adding at least one generic parameter symbol
- create & ppuload: don't create list instance anymore
+ is_generic & is_specialization: check whether the list is assigned
defcmp.pas, compare_defs_ext:
+ check whether "genericparas" list is assigned
pgenutil.pas:
+ check_generic_constraints: check whether "genericparas" is assigned
+ insert_generic_parameter_types: create list before adding generic parameters
git-svn-id: trunk@24627 -
pdecl.pas, types_dec:
* extract the determination of the nested generic def to a new local function "determine_generic_def"
* use "determine_generic_def" to determine the generic def in case of a forward def and pass this and the generic type list to "object_dec"
+ added test
