Hi,
The alias attribute in __attribute__((alias())) is defined as a
function attribute
(http://gcc.gnu.org/onlinedocs/gcc/Function-Attributes.html).
It is not defined as a variable attribute
(http://gcc.gnu.org/onlinedocs/gcc/Variable-Attributes.html).
However, I tried using it for variables (under cygwin on pentium, gcc
version 3.4.4) and it seems to work!
For example,
int AAA;
extern int BBB __attribute__((alias("AAA")));
seems to work properly. And it also creates the proper stabs for
debugging info.
Then my question is: why does the online help (links above) define the
alias attribute for functions only?
- Is there a catch and it doesn't really work?
- Is the help not up to date?
- Or is the grammar general enough such that what works for functions
often automatically works for variables, but you didn't report it?
I need this information in order to check with Texas Instruments whether
they can properly implement the feature on their DSP compilers. It seems
to be only partially implemented there.
Thank you,
Rabih Chrabieh
