91163f167e revert last commit. fails "make test"
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.

31fe1cc62b clarify support for functions returning an array
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.

89059f94c0 refactor post_type() to be explicit about its recursion 2011-03-08 01:47:31 -08:00
Joe Soroka
772b302187 added a note clarifying post_type() recursion
some ancient pre-K&R C allows a function to return an array
and the array brackets to be put after the arguments, such
that "int c()[]" means the same as "int[] c()"

11b2d33523 Add support of asm label for variables.
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.

32a682b88f Fix fct asm label: only valid for declaration
- 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.

e3e5d4ad7a Disable C99 VLA when alloca is unavailable.
* 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

c31dc7aa0c Fix casts from 32bit integer types to 64bit integer types.
This bug was reported in
http://lists.gnu.org/archive/html/tinycc-devel/2010-08/msg00050.html

In this case, we should not emit any code when we cast from VT_FUNC to VT_PTR.

4ab4efd3a6 Revert "implemented C99 for loop with variable declaration"
This reverts commit 433ecdfc9d.

The patch breaks e.g. with
    for ((i = 10); --i;);

In particular to check for a type decl. this is not sufficient:
    if (tok < TOK_UIDENT) {

A future approach to c99 loop variables might instead use:
    if (parse_btype(...)) {

plus refactor function decl() accordingly.
