cclasses.pas:
+ TFPHashList & TFPHashObjectList: add WhileEachCall methods that walk the list like ForEachCall does, but uses a while-loop instead of a for-loop
psub.pas, generate_specialization_procs:
* use WhileEachCall instead of ForEachCall as new defs can be added during the specialization that need to be specialized as well
+ added test
git-svn-id: trunk@25577 -
* For common symbols, report objdata of the original ObjSymbol, not of the resolving one, so the map file shows where it comes from.
+ TElfExeOutput.OrderOrphanSections method, handles object sections not mentioned in script similar to ld.
- t_linux.pas: removed sections that are not part of ld scripts, they are now handled by OrderOrphanSections.

FPHash was duplicated 4 times for different input types. I've
consolidated it to a single function with 3 proxy-functions which can be
inlined.
I've also modified the hash function itself slightly, it now resembled
the original DJB hash and seems to perform a tiny bit better.
git-svn-id: trunk@23850 -
order to minimise memory losses due to alignment padding. Not yet enabled
by default at any optimization level, but can be (de)activated separately
via -Oo(no)orderfields
o added separate tdef.structalignment method that returns the alignment
of a type when it appears in a record/object/class (factors out
AIX-specific double alignment in structs)
o changed the handling of the offset of a delegate interface
implemented via a field, by taking the field offset on demand
rather than at declaration time (because the ordering optimization
causes the offsets of fields to be unknown until the entire
declaration has been parsed)
git-svn-id: trunk@21947 -
o support for the new codepage-aware ansistrings in the jvm branch
o empty ansistrings are now always represented by a nil pointer rather than
by an empty string, because an empty string also has a code page which
can confuse code (although this will make ansistrings harder to use
in Java code)
o more string helpers code shared between the general and jvm rtl
o support for indexbyte/word in the jvm rtl (warning: first parameter
is an open array rather than an untyped parameter there, so
indexchar(pcharvar^,10,0) will be equivalent to
indexchar[pcharvar^],10,0) there, which is different from what is
intended; changing it to an untyped parameter wouldn't help though)
o default() support is not yet complete
o calling fpcres is currently broken due to limitations in
sysutils.executeprocess() regarding handling unix quoting and
the compiler using the same command lines for scripts and directly
calling external programs
o compiling the Java compiler currently requires adding ALLOW_WARNINGS=1
to the make command line
git-svn-id: branches/jvmbackend@20887 -
* eliminate warnings in compiler (i386 & i368->x86_64) and minor refactorings
- comment out unused vars and types
- comment out unneeded comparisons (Longword <=> 0)
- suppress some "comparison always true|false" warnings
- tweak visiblity sections
git-svn-id: trunk@19385 -
- add TTagHashSet class descendant of THashSet with an ability to has also a LongWord value together with key
- change TAsmData.ConstPools[] to be an indexed property to properly initialize ConstPool class, remove pool initialization from all other units
- add ansistring constants to pool together with their encoding to distinct the same text constants with different codepage
+ test
git-svn-id: trunk@19261 -
mangled name handling ansistring rather than pshortstring based (required
for JVM target; little effect on speed, some extra memory usage)
git-svn-id: branches/jvmbackend@18597 -
datasize (and grow with 16 bytes at a time instead of with only
exactly as many bytes as required to accomodate the new element)
git-svn-id: trunk@15603 -
instead of a "div" to truncate the hash to the table size
* prefetch the string we are looking for
- removed the optimization whereby the length and the last character are
checked before the entire string is compared during the hashtable
searching, because this does not help anymore (our hash funcion is
better than when this was added, and we also have a special "equals"
string comparison function nowadays that also first checks the length)
git-svn-id: trunk@15516 -
vmt entries of virtual methods that can never be called with references
to FPC_ABSTRACTERROR. Some virtual methods are always considered to be
reachable: published methods, and methods used as getter/setter for a
published property.
git-svn-id: trunk@13238 -
* Replaces linear search through assembler list by the hash lookup.
This considerably improves performance on large projects
(one example is winunits-jedi package, in which tcgstringconstnode.pass_generate_code
was top #1 in calltree, consuming about 12% IRefs).
* Enables reusing memory locations for widestring constants
(and in general, the same approach may be used for any other type of constants).
* Saves a sizeof(pointer) bytes per constant, by removing a location
which points to the string. This location is necessary for the
typed consts which may be modified, but redundant for string literals
because the language does not allow to modify string literals in any way.
git-svn-id: trunk@11657 -
* 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
