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)

the code using {$pascalmainname x} + storing it in the ppu file
(and give a warning if it's overridden multiple times + test)
git-svn-id: trunk@10406 -
entry/exit (mantis #10897)
* fixed tinterface2 which crashed after this change. It also crashed under
Kylix: you cannot assign the result of an interfaced class to a class
instance variable and then use it both as an interface (refcounted) and
as class (non-refcounted)
git-svn-id: trunk@10405 -
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)
git-svn-id: trunk@10396 -
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)
git-svn-id: trunk@10320 -
because due to the mach-o executable format which can contain
binaries for different architectures in a single file, different
names for native and cross compilers are not used on Mac OS X
(mantis #10067)
git-svn-id: trunk@10270 -
they are added (mantis #10807), because
a) the typecheckpass of the entire blocks has to be postponed until firstpass
because new statements may still be added in the firstpass (otherwise
the newly added statements in the firstpass are never typechecked due to
the blocknode already having a resultdef set)
b) simplify can be called between the typecheck and firstpass, and it needs
the typeinfo

as a parameter and the funcret is also passed as parameter. Because in that
case both are pointing to the same memory location

because the method was always called the same way (and it did not
affect any counting anymore)

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

* -Xg now produces a .dbg file with debuginfo
that can be used by gdb. The main executable gets
a debuglink section that references the .dbg file.

compiler binaries when determining whether cycle has finished
on darwin, because when using Dwarf the linked binaries are
always slightly different there (because the Dwarf info is kept
in the object files and is referenced using a unique identifier,
to be able to ascertain that you are using the correct object
files and binary together when debugging)

already been used for overload selection etc, i.e., semantically
nothing changes)

initialised/finalised, because the init/final generation code
happens after pass 2 using plain nodes and therefore needs the
