Sure. %| was removed due to concerns over some target architectures already use it, but now %| is under ASSEMBLER_DIALECT and doesn't seem to affect them. ChangeLog: 2013-04-29 Maxim Kuznetsov <[email protected]> * final.c (do_assembler_dialects): Don't handle curly braces and vertical bar escaped by % as dialect delimiters. (output_asm_insn): Print curly braces and vertical bar if escaped by % and ASSEMBLER_DIALECT defined. * doc/tm.texi (ASSEMBLER_DIALECT): Document new standard escapes. testsuite/ChangeLog: 2013-04-29 Maxim Kuznetsov <[email protected]> * gcc.target/i386/asm-dialect-2.c: New testcase. -- Maxim Kuznetsov
