Subject: gdb/riscv: Update test to handle targets without an fpu
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=99e1a184a791d30c09a86d6eca4528dc146c2c79;p=binutils-gdb.git

gdb/riscv: Update test to handle targets without an fpu

The FPU is optional on RISC-V.  The gdb.base/float.exp test currently
assumes that an fpu is always available on RISC-V.  Update the test so
that this is not the case.

gdb/testsuite/ChangeLog:

	* gdb.base/float.exp: Handle RISC-V targets without an FPU.
