Strange Linaro mips compiler assembly output

Question

To create assembly code I'm calling the mipsel-openwrt-linux-uclibc-gcc compiler (Linaro GCC 4.8-2014.04 r49389) with flag -S. This produces assembly code looking like this:

        .section .mdebug.abi32
        .previous
        .gnu_attribute 4, 3
        .abicalls
        .option pic0
        .text
    $Ltext0:
        .cfi_sections   .debug_frame
        .globl  Version
        .section    .rodata.str1.4,"aMS",@progbits,1
        .align  2
    $LC0:
        .ascii  "3.3\000"
        .data
        .align  2
        .type   Version, @object
        .size   Version, 4
    Version:
        .word   $LC0
        .text

This doesn't look like AT&T nor Intel syntax to me. To produce more familiar syntax I've tried the -masm=intel flag, but same effect..

My first thougt was the produced ASM code is dedicated to the fixed word width of mips, but any ideas how to generate AT&T or Intel syntax via mipsel-openwrt-linux-uclibc-gcc?

Thanks for any hints!

Answer 1

"What AT&T and Intel syntax have to do with MIPS?" - Nothing directly, I've tagged it that way as tag 'mipsel-openwrt-linux-uclibc-gcc' was not available (sry, maybe bad style). But thanks Margaret your comment directed me to compile some more .c files leading to the expected AT&T syntax :) - f.e.:

        .section .mdebug.abi32
        .previous
        .gnu_attribute 4, 3
        .abicalls

        .text
    $Ltext0:
        .cfi_sections   .debug_frame
        .align  2
    $LFB16 = .
        .file 1 "io.c"
        .loc 1 474 0
        .cfi_startproc
        .set    nomips16
        .ent    prepare_text
        .type   prepare_text, @function
    prepare_text:
        .frame  $sp,48,$31      # vars= 0, regs= 5/0, args= 16, gp= 8
        .mask   0x800f0000,-4
        .fmask  0x00000000,0
        .set    noreorder
        .set    nomacro
    $LVL0 = .
        addiu   $sp,$sp,-48
