- # When returning a floating point value from a function, all known
- # compilers do this via a `fldl' instruction, which pushes the floating
- # value on the i387 stack. This causes two problems:
- # a) Most i*86 targets do not store (or cannot store, see comment in
- # in i386v-nat.c:i386_register_u_addr) the floating point registers
- # to the target.
- # b) gdb would have to figure out if the `fldl' instruction (or variants
- # of it) has already been executed. If not, it would have to simulate
- # a push instruction, as it is not enough to write the register,
- # the floating point `stack pointer' has to be updated too.
- # Do not expect this to get fixed anytime soon.
-
# This test also fails for sparc Solaris 2.3 & 2.4, but passes under 2.5
# At the time the `next' is issued, the floating point unit for the
# process is not yet initialized, and the storing of the floating
# process start, making this test pass, it will be for a version that
# is not xfailed.
