[PATCH] testsuite: arm: Use effective-target for unsigned-extend-1.c

[Torbjörn SVENSSON]

Ok for trunk and releases/gcc-14?

--

A long time ago, this test forced -march=armv6.

With -marm, the generated assembler is:
foo:
        sub     r0, r0, #48
        cmp     r0, #9
        movhi   r0, #0
        movls   r0, #1
        bx      lr

With -mthumb, the generated assembler is:
foo:
        subs    r0, r0, #48
        movs    r2, #9
        uxtb    r3, r0
        movs    r0, #0
        cmp     r2, r3
        adcs    r0, r0, r0
        uxtb    r0, r0
        bx      lr

Require effective-target arm_arm_ok to skip the test for thumb-only
targets (Cortex-M).

gcc/testsuite/ChangeLog:

        * gcc.target/arm/unsigned-extend-1.c: Use effective-target
        arm_arm_ok.
