* tccgen: nodata_wanted fix, default ONE_SOURCE, etc...grischka2017-07-231-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | tccgen.c: doubles need to be aligned, on ARM. The section_reserve() in init_putv does not do that. -D ONE_SOURCE: is now the default and not longer needed. Also, tcc.h now sets the default native target. These both make compiling tcc simple as "gcc tcc.c -o tcc -ldl" again. arm-asm.c: enable pseudo asm also for inline asm tests/tests2/Makefile: disable bitfield tests except on windows and x86_64 and don't generate-always tcc.c: fix a loop with -dt on errors configure: print compiler version (as recognized) tccpp.c: actually define symbols for tcc -dt clear static variables (needed for -dt or libtcc usage) 96_nodata_wanted.c: use __label__ instead of asm lib/files: use native symbols (__i386__ etc.) instead of TCC_TARGET_...

| | | | | | | | | | | | | | | | | | | | | | | | The existing variable 'nocode_wanted' is now used to control output of static data too. So... (nocode_wanted == 0) code and data (normal within functions) (nocode_wanted < 0) means: no code, but data (global or static data) (nocode_wanted > 0) means: no code and no data (code and data suppressed) (nocode_wanted & 0xC0000000) means: we're in declaration of static data Also: new option '-dT' to be used with -run tcc -dT -run file.c This will look in file.c for certain comment-boundaries: /*-* test-xxx: ...some description */ and then for each test below run it from memory. This way various features and error messages can be tested with one single file. See 96_nodata_wanted.c for an example. Also: tccgen.c: one more bitfield fix
* #pragma comment(option,"-..."), bitfields test, etc...grischka2017-07-141-0/+215
tccpp.c: * #pragma comment(option,"-some-option") to set commandline option from C code. May work only for some options. libtcc.c: * option "-d1..9": sets a 'g_debug' global variable. (for development) tests2/Makefile: * new make targets: tests2.37 / tests2.37+ run single test from tests2, optionally update .expect * new variable GEN-ALWAYS to always generate certain .expects * bitfields test tccgen.c: * bitfields: fix a bug and improve slightly more * _Generic: ignore "type match twice"
