(cond ? 0 : ptr)->member wasn't handled correctly. If one arm
is a null pointer constant (which also can be a pointer) the result
type is that of the other arm.
array_test is declared and called with no parameters but defined with
one parameter. Compilation succeed (definition is after the use so the
compiler consider the declaration) as well as link (the function exist
and has the right name) but running the test segfault on i386 platforms.
This patch moves the parameter to local variable. If the intention was
to call it with an array parameter then feel free to fix it again.
* Disable C99 VLA detection when alloca is unavailable and protect the
new reference to TOK_alloca in decl_initializer in order to compile
and run for architecture without working alloca.
Not all code of C99 VLA is commented as it would required many ifdef
stanza. Just the detection is commented so that VT_VLA is never set
any type and the C99 VLA code is compiled but never called. However
vpush_global_sym(&func_old_type, TOK_alloca) in decl_initializer needs
to be protected by an ifdef stanza as well because it uses TOK_alloca.
* include alloca and C99 VLA tests according to availability of
TOK_alloca instead of relying on the current architecture
Implement C99 Variable Length Arrays in tinycc:
- Support VLA with multiple level (nested vla)
- Update documentation with regards to VT_VLA
- Add a testsuite in tcctest.c
- add __builtin_va_arg_types to check how arguments were passed
- move most code of stdarg into libtcc1.c
- remove __builtin_malloc and __builtin_free
- add a test case based on the bug report
(http://www.mail-archive.com/tinycc-devel@nongnu.org/msg03036.html)
- Fix a wrong calculation for size of struct
- Handle cases where struct size isn't multple of 8
- Recover vstack after memcpy for pushing struct
- Add a float parameter for struct_assign_test1 to check SSE alignment
(Because GNU's alloca.h unconditionally #undef's alloca)
Also, remove gcc specific sections in headers. and
instead change tests such that gcc does not use them.
