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_...

* -dt now with lowercase t
* test snippets now separated by real preprocessor statements
which is valid C also for other compilers
#if defined test_xxx
< test snippet x >
#elif defined test_yyy
< test snippet y >
#elif ...
#endif
* simpler implementation, behaves like -run if no 'test_...' macros
are seen, works with -E too
* for demonstration I combined some of the small tests for errors
and warnings (56..63,74) in "60_errors_and_warnings.c"
Also:
* libtcc.c:
put tcc_preprocess() and tcc_assemble() under the setjmp clause
to let them return to caller after errors. This is for -dt -E.
* tccgen.c:
- get rid of save/restore_parse_state(), macro_ptr is saved
by begin_macro anyway, now line_num too.
- use expr_eq for parsing _Generic's controlling_type
- set nocode_wanted with const_wanted. too, This is to keep
VT_JMP on vtop when parsing preprocessor expressions.
* tccpp.c: tcc -E: suppress trailing whitespace from lines with
comments (that -E removes) such as
NO_GOTPLT_ENTRY,\t /* never generate ... */

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
