Siemargl port comments
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
Tests status:
asmtest +
abitest not tested (embedding compiler)
libtcctest not tested (embedding compiler)
boundtest ----- alloca removed from tcc libtcc.c:945 (really not worked)
tcctest most test ok, some problems with long double
vla_test.c +
pp/* + (minor comment error in 13.s)
tests2/* : see below
// errata
skippin' tests
test76 fail dollars in identifiers
test34 fail (array assignment not supported)
test73 fail compile (no stdint.h), printfloat, ARM specific
test46 no stdin - removed funtionality read from console, but file ops works
