[cfe-dev] Probems of semantic analysis for dllimport / dllexport attributes

[Ilya Okonsky]

Hello!

Currently  I'm  working on semantic analysis for dllimport / dllexport
attributes
(http://gcc.gnu.org/onlinedocs/gcc-4.3.2/gcc/Function-Attributes.html#index-g_t_0040code_007b_005f_005fdeclspec_0028dllexport_0029_007d-2126
and
http://gcc.gnu.org/onlinedocs/gcc-4.3.2/gcc/Function-Attributes.html#index-g_t_0040code_007b_005f_005fdeclspec_0028dllimport_0029_007d-2127).
The  main  problem  seen  so  far  is that handling of decl attributes
occurs  very  early  -  before  the  function  body  (if  any) will be
available.  However,  correct  semantic  checks  of  these  attributes
require,  that  information  whether we have declaration or definition
should be available. What is the best place for inserting such checks?
