test target in Makefile does not depend on tcc.
i'm not sure why, but i can think of at least one
good reason. in my local tree I have it modified
to do so, but somehow inadvertently reverted that
so when i did "make test" before committing, it
didn't actually test my changes. sorry.
previously, tcc would accept a prototype of a function returning
an array, but not giving those functions bodies nor calling them.
it seems that gcc has never supported them, so we should probably
just error out... but it's possible that someone already using
tcc includes some header that contains an unused prototype for
one, so let's continue to support that.
- fix my prev commit:
put declaration above statements to stay c89 compatible
- replace commit by a blank
#define con(a, b) a/**/b
this should yield a b, not ab
We need a ' ' after subst of m in the following case
#define m(name,r) name ## r
#define m0(a,b,c) int m(a,b) c
#define m1(a,b,c) int m(a,b)c
m0(a, b, c);
m1(a, b, c);
To make this the default, enable this line in libtcc.c:tcc_new:
#if defined(TCC_TARGET_PE) && 0
s->leading_underscore = 1;
and then recompile tcc and also libtcc1.a
Add support for asm labels for variables, that is the ability to rename
a variable at assembly level with __asm__ ("newname") appended in
its declaration.
See http://gcc.gnu.org/onlinedocs/gcc-4.4.4/gcc/Asm-Labels.html for more
details.
- Fix function assembly label mechanism introduced in commit
9b09fc376e to only accept alternative
name for function declaration.
- merge the code with the one introduced in commit
264a103610.
- Don't memorize token for asm label but directly the asm label.
Error out on static function without file scope and give an explaination
to the user
This is a rewrite of e9406c09a3 but
considering problems raised about static local function pointers in
632ee5a540.
* 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
TOK_alloca is now available on x86-64 so make put definition of
TOK_alloca outside the BCHECK conditional macro definition but test if
arch is i386 or x86-64. This makes C99 VLA works (understand compile) on
x86-64.
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
