for qwordbool) + test:
o assigning true to such a variable now sets them to $ff/$ffff/$ffffffff
o these types are now all signed
o converting an integer type to a byte/word/long/qwordbool using an
explicit type cast keeps the integer's original value stored in the
bool, instead of forcing it to ord(true)/ord(false)
(mantis #10233 and #10613, implemented for all architectures, testsuite
tested for ppc32, sparc and x86)
* fixed some places where the rtl depended on longbool(true) having the
value 1
* extended several boolean tests (and adapted some to no longer assume
that byte/word/long/qwordbool(true)=1)
+ support for converting to qwordbool in second_int_to_bool for x86, ppc
and sparc

of u32bit values on 32 bit platforms (after the int64 values have
already been used for overload selection etc, i.e., semantically
nothing changes)
+ test which checks that not too many typecasts are optimized away
git-svn-id: trunk@9664 -
* small cleanups of unused variables in firstpass
* node_resources_fpu() created to get an approximation of the
required fpu registers
* for the moment use node_complexity in the CG until the
node_resource_int() is created
git-svn-id: trunk@8655 -
is <> 0 (Delphi compatible now, + various tests)
+ support for enums and sets in is_in_limit()
* fixed converting smallset expressions to varsets
* improved choosing an appropriate common set type when mixing
set types in an expression
- removed no longer used normalset code from nadd.pas
- disabled large set (>256 elements) support for now, because
they are not yet supported entirely throughout the compiler
and this causes errors at run time in several situations
git-svn-id: trunk@8515 -
a stringconstn is often an arraydef. The result is that they again
get the same typeconversion behaviour as string variables, which is
important in case of overloaded operators (#9021/#9026)
git-svn-id: trunk@8268 -
- {$intpromotion common_type} or -CIcommon_type switches to common type promotion.
- {$intpromotion native_integer} or -CIcommon_type switches to current behaviour.
- Default in tp mode is common_type, native_integer in other modes
- Compiler can cycle with -CIcommon_type
- Still needs checking on other architectures than i386
git-svn-id: trunk@8118 -
* fixed some (harmless) ptrint warnings
- removed some commented code in agppcmpw
* added one missing field in a typed constant in cp1251
git-svn-id: trunk@8081 -
constant is outside the range of type bounds of the left expression.
I.e. "if a>0" evaluates to true if a is declared with type 1..10,
as all legal values of a are greater than zero.

This is needed to be able to call simplify after pass_1, because
otherwise the inserttypeconv's inserted new type conversions which
where never firstpassed (if you want to do something like that, you
have to return a new node as well so it will be firstpassed properly
-- but in this case it seems this is not needed, since inserting
those typeconversions are part of typechecking and not of simplifying,
and typechecking must be done before simplifying anyway)
git-svn-id: trunk@6836 -
* symtables based on TFPHashObjectList and TFPObjectList
* rename torddef.typ to torddef.ordtype
* rename tfloatdef.typ to tfloatdef.floattype
* rename tdef.deftype to tdef.typ
* remove obsolete browser code, browcol is kept so the ide
can still be compiled
git-svn-id: trunk@5192 -
allow runtime optimization if the destination is the
same as a source parameter
* tassignmentnode now sets aktassignmentnode global that can be used
to use the left node as a destination parameter and
skip the assignment
* disabled all cpu specific shortstr concat/append
git-svn-id: trunk@4770 -
* change booleans in arraydef to set
* set option in arraydef to indicate a constant string so
a nicer type can be shown instead of array[0..x] of char
git-svn-id: trunk@3051 -
32bit*32bit->64bit
+ implemented the above for ppc32 (note: does not happen very often
in practice, at least not in the compiler and rtl)
+ test for the above
git-svn-id: trunk@2735 -
vs_written, vs_readwritten. vs_initialised is the old vs_assigned;
vs_used has been replaced by vs_read, vs_written and vs_readwritten
* the valid_for_*() routines in htypechk now get an extra parameter to
decide whether or not errors should be reported
