it doesn't have to duplicate any type checking code, and so constant
expressions get the same resultdefs as non-constant expressions
* properly fixed resultdef determination of "set + setelementn" (follows
same rules now as "set + set")
* also convert "longint or/xor cardinal" to int64 (needed for correct
results with negative numbers and Delphi-compatible) + test
* extended 64-to-32 type conversion simplification to also handle
or/xor nodes (so if the result is typecasted back to 32 bit, the
evaluation can still be done entirely in 32 bit). These changes also
enable that optimization in some extra cases (not just anymore for
expressions containing only uint32)

pass to pass 1 (where most optimizing transformations are located,
and because the way it's written it goes wrong if left and right are
a constant, and I'm working on moving the simplify code after the
typechecking code so the resulttype for constant and non-constant
expressions can be the same)

a) cpu64bitaddr, which means that we are generating a compiler which
will generate code for targets with a 64 bit address space/abi
b) cpu64bitalu, which means that we are generating a compiler which
will generate code for a cpu with support for 64 bit integer
operations (possibly running in a 32 bit address space, depending
on the cpu64bitaddr define)
All cpus which had cpu64bit set now have both the above defines set,
and none of the 32 bit cpus have cpu64bitalu set (and none will
compile with it currently)
+ pint and puint types, similar to aint/aword (not pword because that
that conflicts with pword=^word)
* several changes from aint/aword to pint/pword
* some changes of tcgsize2size[OS_INT] to sizeof(pint)

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

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

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
