o these classes get an "enum" flag in the class files
o these classes get a class field (whose type is that same enum
class) per enum in the type, which also gets the "enum" flag
o those class fields are initialised in the class constructor
with the name of the enum and their order in the declaration
o if the enum has jumps in FPC (lowest value is not 0, or not
all values are contiguous), then we add an extra field
to hold the FPC ordinal value of the enum
o these classes get a class field valled $VALUES that contains
a reference to the aforementioned class fields in order of
declaration (= ordinal->instance mapping, JDK-mandated)
o apart from the JDK-mandated instance methods (values, valueOf),
also add FPCOrdinal (returns FPC ordinal value; same as order
of declaration in case of no jumps) instance method and FPCValueOf
(returns enum corresponding to FPC ordinal value) static class
method
o the mapping between FPC ordinals and enum instances in case of
jumps is stored in a hashmap whose size is the next prime number
greater or equal than the number of enum elements
o moved several extra JDK types to the system unit for the enum
support, and for future boxing and Java set support
o several new synthetic method identifiers to generate the enum class
methods/constructor/class constructor
o enums with jumps are ordered by FPC ordinal value in the JVM
$VALUES array so that the java.lang.Enum.doCompare() method
will properly compare them

for the current unit and all types/routines declared in it. The
unit itself becomes a member of this namespace as well, so in
case it's called unit1, it will be x.y.z.unit1, and type tclass
declared in it will be x.y.z.tclass. Only used for the JVM
target currently

shortstrings to prevent cut-offs
+ ReplaceCase() ansistring overload in cutils to support the above
* always use the fully qualified name in case of nested types inside
the parameter lists of procdefs
* put extra information about array parameters between {} so they
can be passed back into the parser

alignment for each memory reference (mantis #12137, and
test/packages/fcl-registry/tregistry1.pp on sparc). This also
enables better code generation for packed records in many cases.
o several changes were made to the compiler to minimise the chances
of accidentally forgetting to set the alignment of memory references
in the future:
- reference_reset*() now has an extra alignment parameter
- location_reset() can now only be used for non LOC_(C)REFERENCE,
use location_reset_ref() for those (split the tloc enum so the
compiler can catch errors using range checking)

* Suppressed 2 unreachable code warnings.
* Now x86 compiler compiles without warnings and notes! It will be great to keep such state in future...

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 -
* varsets ({$packset x}) are now supported on big endian targets
* gdb now displays sets properly on big endian systems
* cleanup of generic set code (in, include/exclude, helpers), all
based on "bitpacked array[] of 0..1" now
* there are no helpers available yet to convert sets from the old to
the new format, because the set format will change again slightly
in the near future (so that e.g. a set of 24..31 will be stored in
1 byte), and creating two classes of set conversion helpers would
confuse things (i.e., it's not recommended to use trunk currently for
programs which load sets stored to disk by big endian programs compiled
by previous FPC versions)
* cross-endian compiling has been tested and still works, but one case
is not supported: compiling a compiler for a different endianess
using a starting compiler from before the current revision (so first
cycle natively, and then use the newly created compiler to create a
cross-compiler)
git-svn-id: trunk@7395 -
* 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

are allocated at irregular intervals in between larger allocations
(reduces stack usage of taddnode.det_resulttype on darwin/i386 from
11+kb to 868 bytes; no effect on Darwin/ppc, and a few small
improvements on linux/i386)

+ use {$bitpacking on/+} to change the meaning of "packed"
into "bitpacked" for arrays. This is the default for MacPas.
You can also define individual arrays as "bitpacked", but
this is not encouraged since this keyword is not known by
other compilers and therefore makes your code unportable.
+ pack(unpackedarray,index,packedarray) to pack
length(packedarray) elements starting at
unpackedarray[index] into packedarray.
+ unpack(packedarray,unpackedarray,index) to unpack
packedarray into unpackedarray, with the first
element being stored at unpackedarray[index]
* todo:
* "open packed arrays" and rtti for packed arrays are not
yet supported
* gdb does not properly support bitpacked arrays
