* + optimization that (re)orders instance fields of Delphi-style classes injonas2012-07-221-1/+2
| | | | | | | | | | | | | | | | 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: http://svn.freepascal.org/svn/fpc/trunk@21947 3ad0048d-3df7-0310-abae-a5850022a9f2

* - removed ppc601 as ppc32 cpu targetjonas2007-02-031-4/+8
| | | | | | | | | | | | | | | | | + added ppc740 (g3), ppc7400 (G4) and ppc970 (G5) as ppc32 cpu targets * initialise optimizecputype by default to ppc7400 for ppc32 and to ppc970 for ppc64 * merged ppc32/ppc64 overflow checking code and use the ppc64 one in case cputype or optimizecputype >= ppc970, because one of the instructions used in the ppc32 version no longer exists on the ppc970 (although it's emulated in the kernel on at least Mac OS X) * moved some other support routines and constants to ppcgen which were needed for the overflow checking (were identical for ppc32 and ppc64) git-svn-id: http://svn.freepascal.org/svn/fpc/trunk@6323 3ad0048d-3df7-0310-abae-a5850022a9f2
