39 | # In the case where we are stuck with a compiler that has been uselessly | |
40 | # restricted to a particular ISA, a favourite default of newer GCCs when | |
41 | # extensive multilib targets are not provided, ensure we get the best fit | |
42 | # regarding FP generation. This is necessary to avoid references to FP | |
43 | # variants in libgcc where integer variants exist, which otherwise result | |
44 | # in link errors. This is intentionally stupid (albeit many orders of | |
45 | # magnitude less than GCC's default behaviour), as anything with a large | |
46 | # number of multilib targets better have been built correctly for | |
47 | # the target in mind. | |
