8b7c5666a2 * Renamed fc_block_with_exit to fc_no_direct_exit to expand its usage. 
* Set fc_no_direct_exit in case when a routine has an additional implicit exit code, such as calling FreeInstance in the destructor.

d72566169e * The code generator of the exit statement must set the fc_gotolabel flag in flowcontrol for inlined routines/code blocks. It fixes the incorrect assumption that such exit statements terminate the main routine.

3b9f5a5e96 * moved finalization of code generator temps to a node, so it can be getcopy'd 
(needed for LLVM, where we need two copies of the finally code: one in case
     an exception occurs, and one in case none is raised)
   o also first finalize parameters and only then code generator temps, since
     in theory the former could create more of the latter

bf4eda478d * SetExecutionWeight(): Set execution weight also for nodes with special handling. Minor code cleanup/improvements. 
* Restore previous execution weight before exiting secondpass().
* It all improves register allocation for variables inside loops in some cases.

b14c037533 * record in the flowcontrol flags whether we are currently in a block whose 
exceptions are caught in the current routine (fc_catching_exceptions),
    so that for LLVM we will be able to use "invoke" instead of "call" in that
    case

e542800ea9 * Win64 SEH: Track control flow out of unwind-protected regions in a more precise way and don't generate expensive calls to __fpc_local_unwind when not necessary.

aee5380ae0 * merged trunk up to r20882 
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

b52dcd4a56 * changed var-parameter of secondpass() into a value parameter: secondpass 
should never change any nodes, and this allows passing properties to
    secondpass
