bc47125943 * use BsrDWord in software mod/div 
* use a for loop instead of an until loop so code generation is potentially better

b1b175dacc + Internal linker support for weak symbols. 
+ Allow unresolved external symbols in RemoveUnreferencedSections, such symbols are marked as 'dynamic' if referenced. This approach allows to collect unused sections early and generate import structures only for actually used symbols.

Jonas Maebe
a5cb157091 * enable specifying the alignment mismatch of the frame/stack pointer 
relative to the normal stack alignment of the target (e.g., when using
    ebp as framepointer, all addresses are offset 8 to the stack pointer) in
    the temp generator. This enables allocating temps/locals with the correct
    alignment as long as the required alignment is not bigger than the
    guaranteed stack pointer alignment (fixes mantis #15582 on systems where
    the stack pointer is at least aligned to 16 bytes; e.g., not yet on
    i386-platforms other than darwin)

9feee08eba * mark Java inner interfaces as "static abstract" like javac, solves the 
"Illegal class modifiers in class SomeClass 0x209" when implementing
    such interfaces in code compiled by Eclipse's internal compiler

Jonas Maebe
952ac1ffa6 * only use indirect symbol loads for (weak)external and private_external 
symbols on darwin/ppc and darwin/i386, and also for common symbols on
    darwin/ppc, as they're not required for other kinds of symbols on those
    platforms (gcc doesn't use them either with -O1 and higher; it does use
    them always for darwin/ppc64 except for local symbols, and hence so do we)

c71cb9dc69 * fixed null termination of cmdline (based on patch by C Western, 
mantis #22742) -- that function seems like a good candidate to
    put in a shared include file though

01b5e2b6f6 * use the parsed node type for checking the validity of default parameter 
values instead of a default based on the resulting constsym (more robust)

ad054831bb * save/restore itype and implementsgetter fields of timplementedinterface 
to/from ppu, because it can be required while resolving type casts
