Has anyone already compiled EPICS 7 for VxWorks 6.9 for PPC604?
I have problems:

With -O2 it fails here:

../fdmgr/fdmgr.cpp: In member function 'virtual epicsTimerNotify::expireStatus timerForOldFdmgr::expire(const epicsTime&)':
../fdmgr/fdmgr.cpp:152: error: unable to find a register to spill in class 'FLOAT_REGS'
../fdmgr/fdmgr.cpp:152: error: this is the insn:
(insn:HI 16 15 17 2 ../fdmgr/fdmgr.cpp:151 (set (reg:DF 126 [ D.11913.delay ])
        (mem/s/j/c:DF (plus:SI (reg/f:SI 113 sfp)
                (const_int 8 [0x8])) [0 D.11913.delay+0 S8 A64])) 336 {*movdf_hardfloat32} (expr_list:REG_EQUIV (mem/s/j/c:DF (plus:SI (reg/f:SI 113 sfp)
                (const_int 8 [0x8])) [0 D.11913.delay+0 S8 A64])
        (nil)))
../fdmgr/fdmgr.cpp:152: confused by earlier errors, bailing out

With -O1 (or lower) it comliles the above but then fails here:

../../src/misc/pv/typeCast.h: In function 'void<unnamed>::castVTyped(size_t, void*, const void*) [with TO = std::basic_string<char, std::char_traits<char>, std::allocator<char> >, FROM = float]':
../../src/misc/pv/typeCast.h:195: sorry, unimplemented: inlining failed in call to 'TO epics::pvData::castUnsafe(const FROM&) [with TO = std::basic_string<char, std::char_traits<char>, std::allocator<char> >, FROM = float]': recursive inlining
../../src/misc/typeCast.cpp:38: sorry, unimplemented: called from here

At least the compiler is "sorry".  I feel much better.

BTW: VxWorks 6.7 has no such problems.
