| Commit Comment: | * merged the jvmbackend branch General: o support for Java/JVM and Android/JVM targets, with support for most common language features (classes, records, all array types, enumerations, signed and unsigned integers, currency, threadvar, typed constants, generics, exceptions, ansistring, ...) and limited support for others (such as pointers and formal var/out parameters). See http://wiki.freepascal.org/FPC_JVM/Language for more details o fpcjres utility to pack "resource files" (= any file specified via {$r xxx}, without any processing) into jar files o {$modeswitch unicodestrings} modeswitch that changes "string" into "unicodestring", "char" unto "widechar" and "pchar" into "pwidechar". Note that the latter two are achieved by automatically adding a unit (uuchar) to the uses clause that overrides these types, so it does not (yet) work for the system unit. If this modeswitch is enabled, {$H+/-} switches between string=unicodestring and string=shortstring, but the state of the {$H}-switch has no effect on the definition of char/pchar. o {$namespace x.y.z} directive to set the package namespace of a unit on the JVM target (does not do anything on other targets). Dotted unit names do not yet influence the namespace of generated JVM classes o javapp utility to create Pascal headers from Java class files Compiler: o new high level code generator in the compiler that uses high level type information, including a wrapper that passes everything through to the existing low level code generators for existing native targets (hlcgobj.pas, hlcg2ll.pas, <arch>/hlcgcpu.pas). Several routines have also migrated from ncgutil.pas to hlcgobj.pas o quite a bit of code in ncg*.pas has been converted to use the new high level code generator so that it works for both existing targets and the new JVM target (mostly replacing tcgsize parameters with tdef parameters, or adding some tdef size parameters) -- this one should always be used in common code, tgobj.gettemp() should only be used in architecture-specific code from now on o new tgobj.gethltemp() routine that also specifies the tdef of the requested temp for high level code generator use o tcgpara now also contains the def of the parameter for use by the high level code generator o support for nested routines without making use of a framepointer, by grouping variables accessed from nested routines into a record and passing a pointer to this record to the nested routines (ncgnstld.pas, ncgnstmm.pas) o support for internally generating and parsing Pascal code in the compiler for routine declarations and implementations (symcreat.pas) o parsing a recorddef and an objectdef method declaration has been factored out so this code can be reused by symcreat.pas o support for duplicating and slightly modifying procdefs (symdef.tprocdef.getcopy, symcreat.finish_copied_procdef) o cchartype has been renamed into cansichartype o new TSymStr type that is used as string type for symbols and mangled names. The default is still pshortstring on all platforms, but for the JVM targets it's ansistring because it sometimes needs symbols > 255 characters o it is no longer allowed to use sysutils.executeprocess() from the compiler, except via the the wrapper cfilutil.RequotedExecuteProcess() so that the compiler can correctly deal with the sysutils.executeprocess() limitation of only supporting double quotes o new getpointerdef(def), getsingletonarraydef(def) and getarraydef(def,count) helpers in symdef to create/get reusable pointer/ arraydefs for another def (mostly used for the JVM target currently) o several parameter parsing helpers have been moved from pdecsub.pas to pparautl.pas o the type checking and firstpass for setlength() and copy() has been moved from pinline.pas to ninl.pas so it can be overridden by target- specific versions o commented the ttempinfoflag values in nbas, and the ttemptype flags in globtype o new "reference" ttempcreatenode type, which can be used to create a reference to (~ hold the address of) another node, even on targets that do not support taking the address of an arbitrary memory location and store it into a virtual register (such as the JVM target). o secondpass no longer takes a var-parameter, since it doesn't change the received node o many routines from pmodules.pas and some from nutils.pas have been moved to ngenutil.pas as virtual class methods so they can be overridden with target-specific versions o the code of a single JVM routine is limited to 64KB bytecode, which can be fairly easily reached when having large array constants because they have to be initialized element by element in the unit initialisation code -> -CTcompactarrayinit switch to use alternate (slightly slower) initialisation of arrays on the JVM targets that uses much less code space o it is now possible to override the individual typecheck helpers of ttypeconvnode o most of the code from ptconst.pas has moved to ngtcon.pas, and has been turned into a class that splits most of the parsing and data/code generation for typed constants into separate routines. Separate implementations are now available that either generate initialised data (native targets) or assignment nodes for explicit initialisation at run time (JVM) RTL: o many extra ifdefs to common RTL include files to enable overriding helpers with JVM-specific helpers o some internal move-alternatives for the RTL that also can be overridden by the JVM target to enable sharing more code between managed and native targets Tests: o a number of JVM-specific tests have been added to tests/test/jvm. They can be executed via the provided testall.sh/.bat scripts. Because standard I/O is not yet available in the Java/Android RTL, most regular tests can't be compiled yet. Note: currently, compiling a JVM compiler requires adding ALLOW_WARNINGS=1 to the make command line |
