* correct -E output for the case ++ + ++ concatenation
do this only for expanded from macro string
and only when tcc_state->output_type == TCC_OUTPUT_PREPROCESS
- uses new `TinyAlloc`-ators for small `TokenSym`, `CString` and
`TokenString` instances
- conditional `TAL_DEBUG` for mem leaks and double frees detection
- on `TAL_DEBUG` collects allocation origin (file + line)
- conditional `TAL_INFO` for allocators stats (in release mode too)
- chain a new allocator twice current capacity on buffer exhaustion
parse_print_line_comment() and parse_print_comment() are
combined and made more simply:
* don't worry about speed with -E option
* don't handle straya in comments
Do we need to handle strays in regular
parse_line_comment() and
parse_comment() ?
A problem was in TOK_ASMDIR_text:
- sprintf(sname, ".%s", get_tok_str(tok1, NULL));
+ sprintf(sname, "%s", get_tok_str(tok1, NULL));
When tok1 is '.text', then sname is '..text'

Subject: Allow tcc arguments to be read from @listfiles
This allows all @ prefixed arguments to be treated as listfiles
containing list of source files or tcc options where each one is on a
separate line. Can be used to benchmark compilation speed with
non-trivial amount of source files.
The impl of `tcc_parse_args` had to be moved to a new function that is
able to be called recursively w/ the original one remaining as a driver
of the new one. Listfiles parsing happens in a new
`args_parser_add_listfile` function that uses `tcc_open`/`tcc_close/inp`
for buffered file input.

Subject: win32: Add missing header files for nginx compilation
The new ones are hoisted from mingw-w64 as most other headers under

Subject: Add VS2015 solution and project files to `win32/vs2015`
directory
This allows release/debug builds for both x86 and x64 targets. Some
warnings had to be suppressed.
Output libtcc.dll and tcc.exe are copied to parent `win32` directory
w/ a post-build action.

Subject: Fix pragma once guard when compiling multiple source files
When compiling multiple source files directly to executable cached
include files guard was incorrectly checked for TOK_once in ifndef_macro
member.
If two source files included the same header guarded by pragma once, then
the second one erroneously skipped it as `cached_includes` is not cleared
on second `tcc_compile`
When tccboot kernels compiles with
'Identifiers can start and/or', this kernel don't start.
It is hard to find what is wrong.
PS: there was no test for identifiers in *.S with '.'
This only silences "cannot find library" error and allows Makefiles targeting gcc to not complain about missing libraries
If there is custom libm then standard handling applies.
There was already support for -dD option but in contrast -dM dumps only `#define` directives w/o actual preprocessor output.
The original -dD output differs from gcc output by additional comment in front of `#define`s so this quirk is left for -dM as well.
From gcc docs: "You may also specify attributes between the enum, struct or union tag and the name of the type rather than after the closing brace."
Adds `82_attribs_position.c` in `tests/tests2`
made like in pcc
(pcc.ludd.ltu.se/ftp/pub/pcc-docs/pcc-utf8-ver3.pdf)
We treat all chars with high bit set as alphabetic.
This allow code like
#include <stdio.h>
int Lefèvre=2;
int main() {
printf("Lefèvre=%d\n",Lefèvre);
return 0;
}
modified version of the old one which don't allow '.'
in #define Identifiers. This allow correctly preprocess
the following code in *.S
#define SRC(y...) \
9999: y; \
.section __ex_table, "a"; \
.long 9999b, 6001f ; \
// .previous
SRC(1: movw (%esi), %bx)
6001:
A test included.
This reloction must copy initialized data from the library
to the program .bss segment. Currently made like for ARM
(to remove noise of defaukt case). Is this true?
remove non-existent or duplicate directories from include paths
if -fnormalize-inc-dirs is specified. This will help
to compile current coreutils package
- Identifiers can start and/or contain '.' in PARSE_FLAG_ASM_FILE
- Move all GAS directives under TOK_ASMDIR prefix
This patches breaks compilation of the tccboot (linux 2.4.26
kernel). A test.S which fails with this patches:
#define SRC(y...) \
9999: y; \
.section __ex_table, "a"; \
.long 9999b, 6001f<---->; \
.previous
SRC(1:<>movw (%esi), %bx<------>)
// 029-test.S:7: error: macro 'SRC' used with too many args
the check on incomplete struct/union/enum types was too early,
disallowing mixed specifiers and qualifiers. Simply rely on
the size (->c) field for that. See testcases.
