Subject: tests/tcg: target/mips: Add a header with test utilities
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=08857c882d1da40793c3be27ae78cb3752902856;p=qmiga%2Fqemu.git

tests/tcg: target/mips: Add a header with test utilities

Add a header that contains test utilities. For now, it contains
only a function for checking and printing test results for bit
counting and similar MSA instructions.
