| 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 | -how to use packed attribute see test82 |
||
| 25 | -alias attribute wont work |
||
| 26 | -unnamed structs in union may lead to compiler internal error |
||
| 27 | -tcc: error: undefined symbol '__tcc_cvt_ftol' |
||
| 28 | --in config.h - used workaround (#define COMMIT_4ad186c5ef61_IS_FIXED |
||
| 29 | --but this is precision bugfix - see \tests\tests2\000_cvttoftol.c |
||
| 30 | -not working: default search path are ./include ./lib from executable |
||
| 31 | --under KOS need to use -Bpath_to_ktcc |
||
| 32 | --start.o not found using -B (kos) - put near your.c file |
||
| 33 | -if static var sized more than 14096+ -> crash compiled .exe (kos) |
||
| 34 | ---^ stack size set in menuet header at compile time tccmeos.c:177 about 4k |
||
| 35 | |||
| 36 | Tests status: |
||
| 37 | asmtest + |
||
| 38 | abitest not tested (embedding compiler) |
||
| 39 | libtcctest not tested (embedding compiler) |
||
| 40 | boundtest ----- alloca removed from tcc libtcc.c:945 (really not worked) |
||
| 41 | tcctest most test ok, some problems with long double |
||
| 42 | vla_test.c + |
||
| 43 | |||
| 44 | pp/* + (minor comment error in 13.s) |
||
| 45 | |||
| 46 | tests2/* : see below |
||

| 48 | // errata |
||
| 49 | skippin' tests |
||
| 50 | test76 fail dollars in identifiers |
||
| 51 | test34 fail (array assignment not supported) |
||
| 52 | test73 fail compile (no stdint.h), printfloat, ARM specific |
||
| 53 | test46 no stdin - removed funtionality read from console, but file ops works |
||
| 54 | |||
| 55 | |||
| 56 | libc: |
||
| 57 | -no "finished" in title of console program after exit console - use con_exit() |
||
| 58 | -bench timing error (0s or 1s) |
||
| 59 | -minimal memory allocator |
||
| 60 | |||
