20 | # This should work on any targets that support MIPS16 execution, including | |
21 | # Linux and bare-iron ones, but not all of them do, for example MIPS16 | |
22 | # support has been added to Linux relatively late in the game. Also besides | |
23 | # environment support, the target processor has to support the MIPS16 ASE. | |
24 | # Finally as of this writing MIPS16 support has only been implemented in the | |
25 | # toolchain for a subset of ABIs, so we need to check that a MIPS16 | |
26 | # executable can be built and run at all before we attempt the actual test. | |
