Ruslan Kabatsayev b593e3d9b0 Fix wrong output of x87 registers due to truncation to double on amd64 ... When `info float` is used on an AMD64 system, GDB prints floating-point values of x87 registers with raw contents like 0x361a867a8e0527397ce0 or 0xc4f988454a1ddd3cfdab wrongly. This happens due to truncation to double, after which the former becomes 0.0, and the latter becomes negative infinity. This is caused by failed detection of x86-64 host, which results in setting gdb_host_{float,double,long_double}_format to zeros. This commit fixes this misdetection, and adds a test to make sure future commits don't introduce a regression here. gdb/ChangeLog: 2015-12-09 Ruslan Kabatsayev <b7.10110111@gmail.com> PR gdb/18702 * configure.host: Fix detection of x86_64 host when setting floatformats. gdb/testsuite/ChangeLog: 2015-12-09 Ruslan Kabatsayev <b7.10110111@gmail.com> Pedro Alves <pedro@redhat.com> PR gdb/18702 Add checking of floatformats setup on x86_64 hosts. * gdb.arch/i386-float.S (main): Load bigval and smallval.
