Used github branch https://github.com/TinyCC/tinycc
|
|
It have a vesion 0.9.26 with heads up to 0.9.27 - see ChangeLog
|
|
|
|
Kolibri version specifics
|
|
errata/changelog - moved to trunk/readme.txt
|
|
|
|
-added TCC_TARGET_MEOS as needed
|
|
-leading_underscore by default is 0 (can use -f[no-]leading-underscore),
|
|
otherwise (error) underscoring all symbols, not only cdecl
|
|
-added message in tccmeos.c about missed symbols when linking KOS executable
|
|
-start.o added automatically, when -nostdlib not used
|
|
-to use standard ktcc lib must add -lck at commandline
|
|
-default search paths are ./include ./lib from executable (under KOS need to
|
|
use -Bpath_to_ktcc and put start.o in current dir)
|
|
-when config.h is ready, compiler can be easy builded as [kos32-]gcc tcc.c libtcc.c
|
|
see also makefile.kos32
|
|
-impossible using with mingw-gcc compiled lib, incompatible library format:
|
|
.o is PE-format from gcc but ELF from tcc, may be linux-gcc does it ok
|
|
-__fastcall incompatible with other compilers. now stack freed by caller.
|
|
must fix i386-gen.c@490,572 (fixed in other branch https://github.com/mirror/tinycc)
|
|
|
|
|
|
-using __attribute__((packed)) see test82. need naming struct twice as in kos32sys1.h
|
|
-using __attribute__ ((alias xxx)) restricted only for non "static inline" functions
|
|
-erroneous or "non TCC" member using in nested structs or unions can lead to compiler internal error
|
|
-bench timing coarse (0s or 1s), no usec in newlib gettimeofday. OK
|
|
