hello there
normally, when I compile and link an executable with the cgt6, I would expect to see holes in the produced map that are in the range of a couple of bytes, like
...
87ba7444 00000145 c64pprocess.cpp.obj (.const)
87ba7589 00000003 --HOLE-- [fill = 0]
87ba758c 0000013e rts64plus.lib : xlocale.obj (.const)
87ba76ca 00000002 --HOLE-- [fill = 0]
87ba76cc 00000001 bios_NONINST.a64P : mbx_crea.o64P (.const)
87ba76cd 00000003 --HOLE-- [fill = 0]
87ba76d0 0000010c libtait-framework-main.r64P (.const)
87ba77dc 00000001 bios_NONINST.a64P : sem_crea.o64P (.const)
87ba77dd 00000003 --HOLE-- [fill = 0]
...
to align sections and symbols. when I do this for a huge project (i.e. the final executable would be in the range of 5MB) the linker starts to introduce holes of random sizes that can go up to a couple of kB (!). when I remove the largest library, it would behave normal again (besides the complaints about the missing symbols, of course). it seems to me like this erroneous behaviour is somehow coupled to the size of the total executable. is there a limit on the size or number of sections/objects the linker can cope with?
unfortunately, i can't boil it down to a limited set of files, nor am i allowed to supply the full set of input files.
but here's the linker command line:
cl6x --run_linker --absolute_exe --map_file=tait-c64pdsp.map --verbose_diagnostics --trampolines=on --disable_auto_rts --warn_sections --issue_remarks --reread_libs --rom_model --search_path=/home/nobss/Work/DBS/build/tmp/cross/c64p/lib --localize=*TID_i* --localize=*TID_v* --localize=*TID_Q2_3* --localize=*TID_Q3_3* --localize=*TID_Q3_5* --localize=*TID_Q4_4* --localize=*TID_Q5_4*
--output_file=tait-c64pdsp.x64P <object-files> <libraries> linker.cmd
and that's the linker file:
/* Do *not* directly modify this file. It was */
/* generated by the Configuration Tool; any */
/* changes risk being overwritten. */
/* INPUT bios_.cdb */

i'm using the 6.1.13 version of the code generation tools.
any ideas?
cheers,
