  1. Siemargl port comments
  2.  
  3. Used github branch https://github.com/TinyCC/tinycc
  4. It have a vesion 0.9.26 with heads up to 0.9.27 - see ChangeLog
  5.  
  6. Kolibri version errata/changelog:
  7.  
  8. -added TCC_TARGET_MEOS as needed
  9. -leading_underscore by default is 0 (can use -f[no-]leading-underscore),
  10. otherwise (error) underscoring all symbols, not only cdecl
  11. -added message in tccmeos.c about missed symbols when linking KOS executable
  12. -start.o added automatically, when -nostdlib not used
  13. -to use standard ktcc lib must add -lck at commandline
  14. -default search paths are ./include ./lib from executable (under KOS need to
  15.  use -Bpath_to_ktcc and put start.o in current dir)
  16. -when config.h is ready, compiler can be easy builded as [kos32-]gcc tcc.c libtcc.c
  17.  see also makefile.kos32
  18. -silent (kos) -> writes to debugboard
  19. -impossible using with mingw-gcc compiled lib, incompatible library format:
  20.  .o is PE-format from gcc but ELF from tcc, may be linux-gcc does it ok
  21. -no symbols (mapfile) for debug, see howtodebugtcc
  22.  
  23.  
  24. -using __attribute__((packed)) see test82. need naming struct twice as in kos32sys1.h
  25. -using __attribute__ ((alias xxx)) restricted only for non "static inline" functions
  26. -erroneous or "non TCC" member using in nested structs or unions can lead to compiler internal error
  27. -not working: default search path are ./include ./lib from executable
  28. --under KOS need to use -Bpath_to_ktcc
  29. --start.o not found using -B (kos) - put near your.c file
  30. -if static var sized more than 14096+ -> crash compiled .exe (kos)
  31. ---^ stack size set in menuet header at compile time tccmeos.c:177 about 4k
  32. -bench timing coarse (0s or 1s), no usec in newlib gettimeofday. OK
  33.  
  34. Tests status:
  35. asmtest +
  36. abitest not tested (embedding compiler)
  37. libtcctest not tested (embedding compiler)
  38. boundtest ----- alloca removed from tcc  libtcc.c:945 (really not worked)
  39. tcctest most test ok, some problems with long double
  40. vla_test.c +
  41.  
  42. pp/* +  (minor comment error in 13.s)
  43.  
  44. tests2/* : see below
  45.  
  46. // errata
  47. skippin' tests
  48. test76 fail dollars in identifiers
  49. test34 fail (array assignment not supported)
  50. test73 fail compile (no stdint.h), printfloat, ARM specific
  51. test46 no stdin - removed funtionality read from console, but file ops works
  52.  
  53.  
  54. libc:
  55. -no "finished" in title of console program after exit console - use con_exit()
  56. -used system memory allocator (4096 bytes minimum)
  57.  
  58.

  62. limits.h
  63. locale.h
  64. setjmp.h
  65. signall.h
