5c67fcc43f + change always floating point divisions into multiplications if they are a power of two,
this is an exact operation so it is always allowed
* change only divisions by normal numbers into multiplications

6f5a648516 Improve the cpu type handling for M68k just in case we should branch 2.8.0 before I can start working on M68k again.
Therefor the cpu type (-Cp...) "coldfire" was split up into "isaa", "isaa+", "isab" and "isac". The Linux RTL can currently compiled for "68020", "isab" and "isac". For the other three Bcc.L must be handled differently (only Bcc.B/W supported) and for "68000" also EXT.L needs to be handled differently.

fpcdefs.inc:
  + define CPUCAPABILITIES if capabilities can be set for a certain CPU type (currently ARM, AVR and M68k)
options.pas:
  * check for CPUCAPABILITIES instead of specific CPUs
assemble.pas:
  - the handling of the CPU type is already done in m68k/ag68kgas.pas, Tm68kGNUAssembler.MakeCmdLine (and thereby already using the gascputypestr array!)
m68k/cpuinfo.pas:
  - tcputype: remove "cpu_coldfire"
  + tcputype: add "cpu_isa_a", "cpu_isa_a_p", "cpu_isa_b" and "cpu_isa_c"
  + add "cpu_coldfire" constant which contains all Coldfire specific cpu types
  * adjust "cputypestr" and  "gascputypestr"
  + add tcpuflags and cpu_capabilities (DBRA restriction was checked with CPUCOLDFIRE, CAS/TAS will be needed for atomic operations and BRAL restriction was discovered during testing of new cpu types)
m68k/cgcpu.pas:
  * adjust checks for "cpu_coldfire"
m68k/n68kadd.pas:
  * don't use a BRA.L if it is not supported, but (at least for now) a BRA.W
aggas.pas:
  * adjusted check for Coldfire

4d86d25c6c * -O4 switch for optimizations which are correct but which might have unexpected effects
like field reordering (possible problems cracker classes) or using ebp as normal register (broken
      stack traces from dump_stack)
    + niln is also valid in a cse domain
    * parameters passed by reference shall have a complexity >1
    * load nodes from outer scopes shall have a complexity >1
    * better cse debugging
    + more node types added to cse
    * consider parameters passed by reference in cse
    * take care of cse in parameters in simple cases

3798b79fd7 + optimization that (re)orders instance fields of Delphi-style classes in
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)

8a6ebdf274 - disabled loop unrolling for level 3 optimizations since it only causes
crashes (and even if it didn't, on its own it mainly causes code
    bloat)

8bc4e0a32f * inline and compilerproc are now procoptions instead of proccall types
(so both can be combined with each other, as well as with other calling
     conventions)
