------- Comment #1 from d dot g dot gorbachev at gmail dot com 2010-03-10 11:17 ------- Machine-independent templates are described in gccint.info, in the "Output Templates and Operand Substitution" section. Online documentation is here: <http://gcc.gnu.org/onlinedocs/gccint/Output-Template.html>. See also: <http://gcc.gnu.org/viewcvs/trunk/gcc/final.c?revision=157325&view=markup#l3194>.
But it seems that x86-specific templates are not documented; see description of them in the sources: <http://gcc.gnu.org/viewcvs/trunk/gcc/config/i386/i386.c?revision=157325&view=markup#l11384>. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43319
