* -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 ... */

Only native compilers support -run and hence the new -dT.

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

- configure
* use aarch64 instead of arm64
- Makefile
* rename the custom include file to "config-extra.mak"
* Also avoid "rm -r /*" if $(tccdir) is empty
- pp/Makefile
* fix .expect generation with gcc
- tcc.h
* cleanup #defines for _MSC_VER
- tccgen.c:
* fix const-propagation for &,|
* fix anonymous named struct (ms-extension) and enable
-fms-extension by default
- i386-gen.c
* clear VT_DEFSIGN
- x86_64-gen.c/win64:
* fix passing structs in registers
* fix alloca (need to keep "func_scratch" below each alloca area on stack)
(This allows to compile a working gnu-make on win64)
- tccpp.c
* alternative approach to 37999a4fbf3487b363fd0c2f9b7ab622401b202a
This is to avoid some slowdown with ## token pasting.
* get_tok_str() : return <eof> for TOK_EOF
* -funsigned-char: apply to "string" literals as well
- tccpe/tools.c: -impdef: support both 32 and 64 bit dlls anyway

- configure:
- add --config-uClibc,-musl switch and suggest to use
it if uClibc/musl is detected
- make warning options magic clang compatible
- simplify (use $confvars instead of individual options)
- Revert "Remove some unused-parameter lint"
7443db0d5f841b81a55e918bf8c228dd20f9ddb2
rather use -Wno-unused-parameter (or just not -Wextra)
- #ifdef functions that are unused on some targets
- tccgen.c: use PTR_SIZE==8 instead of (X86_64 || ARM64)
- tccpe.c: fix some warnings
- integrate dummy arm-asm better

The real equivalence is between the original "s" + (i<2)
and &"s"[i<2].
|
| |
|
|
|
|
| |
"s"[i<2] and "s" + (i<2) are literally identical, but the latter triggers
a warning from clang because it looks so much like a noob is trying to
concatenate an integer and a string. The former is arguably more clear.

Mark TCCState parameter as unused in tcc_undefine_symbol(), tcc_add_symbol(),
tcc_print_stats(), asm_get_local_label_name(), use_section1(), tccpp_delete(),
tcc_tool_ar(), tcc_tool_impdef(), and tcc_tool_cross().
Also mark it unused in tcc_add_bcheck() unless CONFIG_TCC_BCHECK.
Remove it entirely in ld_next().

- configure/Makefiles: minor adjustments
- build-tcc.bat: add -static to gcc options
(avoids libgcc_s*.dll dependency with some mingw versions)
- tccpe.c/tcctools.c: eliminate MAX_PATH
(not available for cross compilers)
- tccasm.c: use uint64_t/strtoull in unary()
(unsigned long sometimes is only uint32_t, as always on windows)
- tccgen.c: Revert (f077d16c) "tccgen: gen_cast: cast FLOAT to DOUBLE"
Was a rather experimental, tentative commit, not really necessary
and somewhat ugly too.
- cleanup recent osx support:
- Makefile/libtcc.c: cleanup copy&paste code
- tccpp.c: restore deleted function

usage:
tcc -ar [rcsv] lib files...
tcc -impdef lib.dll [-v] [-o lib.def]
also:
- support more files with -c: tcc -c f1.c f2.c ...
- fix a bug which caused tcc f1.c f2.S to produce no asm
- allow tcc -ar @listfile too
- change prototype: _void_ tcc_set_options(...)
- apply -Wl,-whole-archive when a librariy is given
as libxxx.a also (not just for -lxxx)
