01a0d7f57b Subject: [PATCH] rs6000: Fix logic for when to emit .machine (PR71216)
The current logic determining whether to use .machine in the generated
asm code puts it there if the compiler is not configured with a default
target cpu, _or_ no -mcpu= was given on the command line.  It should
be "and" instead.

4114e6b1fe compiler: fix check for duplicate declaration
The compiler check that issued a duplicate declaration error for
        a, a, a := 1, 2, 3
    was incorrectly issuing an error for
        a, a, a = 1, 2, 3
    While this is not particularly useful, it is valid Go.
    
    Test is https://golang.org/cl/25143.

a1b01d3403 [ARM] Fix PR target/59833
For Aurelien Jarno <aurelien@aurel32.net>

On ARM soft-float, the float to double conversion doesn't convert a sNaN
to qNaN as the IEEE Std 754 standard mandates:

"Under default exception handling, any operation signaling an invalid
operation exception and for which a floating-point result is to be
delivered shall deliver a quiet NaN."

Given the soft float ARM code ignores exceptions and always provides a
result, a float to double conversion of a signaling NaN should return a
quiet NaN. Fix this in extendsfdf2.

gcc/ChangeLog:

	PR target/59833
	* config/arm/ieee754-df.S (extendsfdf2): Convert sNaN to qNaN.

gcc/testsuite/ChangeLog:

	* gcc.dg/pr59833.c: New testcase.
