tcc -dt -run ... : simpler is better * -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 ... */

Fix array pointer stringification. `int (*)[4];` should not be stringified as `int *[4];` Add stringification tests.

Fix crash on invalid code like on 'enum myenum { L = -1 } L;'. It's a bit tedious as there are two paths (for global vs local symbols), and because the scope and enum_val share same storage.

Handle corner case for abstract decls sometimes abstract decls in parameter lists left the returned name uninitialized potentially leading to segfaults, like in int f(int ()) { return 0; } Deal with this.

[test_abstract_decls]
60_errors_and_warnings.c:141: error: identifier expected
Detect more invalid initializers in presence of invalid source code we can't rely on the next token to determine if we have or haven't already parsed an initializer element, we really have to track it in some separate state; it's a flag, so merge it with the other two we have (size_only and first). Also add some syntax checks for situations which formerly lead to vstack leaks, see the added testcases.

Fix local extern vardecl see testcases. A local 'extern int i' declaration needs to refer to the global declaration, not to a local one it might be shadowing. Doesn't seem to happen in the wild very often as this was broken forever.

Detect invalid VLA decls see testcase, when the inner array dimension of multi-dimensional VLAs isn't given TCC was generating invalid vstack accesses. Those are actually invalid, so just diagnose them.
