[Bug inline-asm/65897] New: GAS named variable of extended asm (::"m" or "g") is in wrong code style, variable stays still in ".att_syntax" -32(%ebp) not ".intel_syntax noprefix" DWORD PTR [ebp-0x20] while rest of the code is switched on corectly

            Bug ID: 65897
           Summary: GAS named variable of extended asm (::"m" or "g") is
                    in wrong code style, variable stays still in
                    ".att_syntax" -32(%ebp) not ".intel_syntax noprefix"
                    DWORD PTR [ebp-0x20] while rest of the code is
                    switched on corectly
           Product: gcc
           Version: 4.8.1
            Status: UNCONFIRMED
          Severity: blocker
          Priority: P3
         Component: inline-asm

simple code as below:
int val;
asm volatile (".INTEL_SYNTAX noprefix\n mov eax,%[val]\n" :: [val] "g" [&val]
asm volatile (".ATT_SYNTAX\n");

is compiled into-> mov eax,-32(%ebp)

rather than correct version for Intel syntax:

-> mov eax,DWORD PTR[ebp-0x20]

First of all i thunk it was capital problem (INTEL not .intel) but it's not.
BTW. Why generated /APP /NO_APP rather than #APP #NO_APP? 
When i switch on -masm=intel globally and disable .intel_syntax in my inline
asm() it compiles whole code correctly(as above). 
When I make ATT code after asm(".att_syntax\n movl -32(%ebp),%eax\n" :: [val]
"g" (&val)); + .intel switched globaly ON, code generated for val stays in
"att" so, no error produced, compilation successed. It's happens either when
syntax is double changed into one asm() statement, 2 statements(as posted), or
three .intel + code + .att, Code .s for named variable is always formated wrong
(as default in ATT mode). Any other code even with global variables is produced
okey, asembler code is working but not when i add named variable (extended
assembly). Even if gcc optimizes val into registry, produces %eax rather than
eax output so it must be a bug not a feature.

I know there is =r, r mode. But for me it's bad that GCC don't know what
register names im using in inline asembly, GAS it's not. Named variables it's
only way to force asm for using locals, "g" mode, 
#__VA_ARGS__ myasm() = myasm_vars() defs is the only way for simpler ported
code.
