[fpc-devel] progress of freepascal for mips

[Fuxin Zhang]

hi everybody,

  With the attached patch (against revision 21440), most of the tests can
now pass, for example, the test directory has only the following
failinglist:

foxsen at ubuntu-zfx:~/software/fpc/tests/output/mipsel-linux$ cat
faillist.testlog
test/cg/taddcurr //the Currency support is broken
test/cg/tcalext  //no ctest.o
test/cg/tcalext3
test/cg/tcalext4
test/cg/tcalext5
test/cg/tcalext6
test/cg/tcnvint4
test/cg/tcnvint6
test/cg/tcppcl1
test/cg/tcppcl2
test/cg/tdivz2
test/cg/tnot
test/cg/tprintf
Note: This test requires a C library
test/cg/tprintf2

test/cg/treadwrt

    don't define cpuflags for mips
    is_calljmp should include float branches: BC1T/BC1F
    no likely branch support: delete bc1tl/bc1fl for now
    new implementation for getting next fpu registers for LDC1/SDC1

    Commit all accumulated fixes:
     1, add -Xs- -g to Makefile to retain symbols and debug info (removed)
     2, systems/i_linux.pas: first_parm_offset set to 0
     3, rtl/inc/systemh.inc: FPC_HAS_INTERNAL_SAR_DWORD for mips
     4, rtl/linux/{ostypes.inc, linux.pp, oldlinux.pp}, macro definitions
for mips: MAP_xxx
     5, rtl/linux/mips/syscall.inc: don't use second stack
     6, mips/*:
          remove the use of NR_TCR*, allocate temporary registers instead
          use fake instructions A_BA/A_BC to handle all kinds of branches,
remove other condition branch instructions, remove all likely
branch
          add support for boolean64
          fix ldc1/sdc1 next register calculation
          use r25 for interface call to better suite abi
          fix inverse_cond
          add bc1t/bc1f to is_calljmp

The next major one should be parameter passing, and then the PIC support.

Thank you for all your kind help.

Regards
