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()"

a3ebdd0aeb tccpe: support leading underscore for symbols 
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

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.
