* * Improvements of tprocinfo class:sergei2011-03-271-0/+65
| | | | | | | | | | | * Moved nestedprocs from tcgprocinfo to tprocinfo, in order to be able to access the entire nested procedure hierarchy without depending on psub.pas or code generator. * Creating an instance of tprocinfo automatically inserts it into list of parent's nested procedures. * nestedprocs list is created on demand. Public read-only access is provided by has_nestedprocs and get_first_nestedproc functions. + Method destroy_tree is provided for destroying the entire hierarchy of procinfo's. It can be called on any procinfo object in the tree. + Also added methods save_jump_labels and restore_jump_labels for asmlabel maintenance, which is currently being repeatedly done all over the codegenerator. git-svn-id: http://svn.freepascal.org/svn/fpc/trunk@17197 3ad0048d-3df7-0310-abae-a5850022a9f2

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) git-svn-id: http://svn.freepascal.org/svn/fpc/trunk@12719 3ad0048d-3df7-0310-abae-a5850022a9f2
