The stack was not aligned when a returned structure was stored on stack.
This resulted in destoying of previous values stored on stack.
See testcase 119 (tst_struct_return_align) where value d is overwritten.
tccgen.c:
- just track local_stack for small scopes (can't declare variables)
- fix a vla problem with nested scopes
- move debug N_L/RBRAC into curly braced block
Also:
- tccpp.c: move 'label_...' functions to tccgen.c
- tccpp.c: let get_tok_str() say "<no name>" for anonymous symbols
- tcctest.c: let __pa_symbol() work for memory > 2GB
- 119_random_stuff.c: revert strtoll test (no reason to test libc)
- tccdefs.h/tcctest.c: enable bit fncs for _WIN32
- Makefile:
- use i686-linux-gnu instead of i386-linux-gnu for cross-i386
- update 'make help'
- revert umplicit 'make all' with 'make install' (but print warning)
Fix for external functions as pointers in data section.
See testcase 119 and tccmacho.c in check_relocs.
Make bind/rebase code faster in bind_rebase_import.
- Move reloc check out of loop
- Because relocs are sorted we can do bind/rebase by page.
Change name head into seq in trie code.
Remove unused code in bind_rebase.
implement load/store to constant address
use VT_LLONG instead of VT_PTR in register passing
fix bound checking problem with small structs
enable riscv tests in tests/tcctest.c and tests/tests2/119_random_stuff.c
Please respect some conventions:
- tests2 filenames don't end with '..._test'
- tests2 tests are meant to produce some output
- the output should be somehow informative, not just
"error" or "dummy". Because other people would want to
know where it fails if it does.
- tests2 tests should work with both GCC and TCC, except
if there are specifc reasons (like testing tcc-only
feature such as bounds checking)
- tests2 tests should never crash or abort. Because that
would cause gui dialogs to pop up on windows, and because
other people would not know where it fails if it does.
- tests2 tests should be somehow specific, in general.
(rather than just collections of random stuff)
- in general, do not use 'long' if you mean 'larger than int'
Because it isn't on many platforms.
- use four (4) spaces for block indention. Do not insert
tab characters in files if possible.
Also:
- tccgen.c:gen_cast() simplify last fix.
