About macro: SYMBOL_REF_SMALL_P

[ibanez]

I'm trying to trace the source code of gcc/mips.
It uses a SYMBOL_REF_SMALL_P macro,
According to the index of 'GNU Compiler Collection Internals',
it should be documented on section RTL representation-Access to Special
Operands but it's not.
How can I find it's document?

My english is very poor.
thank you for your reading :)

I see what you mean...

---------------------------------------------------------------------
@findex SYMBOL_REF_SMALL_P
@findex SYMBOL_FLAG_SMALL
@item SYMBOL_FLAG_SMALL
Set if the symbol is located in the small data section.
See @code{TARGET_IN_SMALL_DATA_P}.
---------------------------------------------------------------------

(the point being that the itemised list only mentions SYMBOL_FLAG_SMALL,
not SYMBOL_REF_SMALL_P).  But the idea is that:

   SYMBOL_REF_SMALL_P (X)

is equivalent to:

   (SYMBOL_REF_FLAGS (X) & SYMBOL_FLAG_SMALL) != 0

where SYMBOL_FLAG_SMALL is as documented.  The same is true for
the other *_P macros.
