2020-12-03compiler: defer to middle-end for complex divisionIan Lance Taylor3-2455/+4170

2020-12-02compiler: reword "declared and not used" error messageIan Lance Taylor2-15/+5
This is a gofrontend copy of https://golang.org/cl/203282. From the CL 203282 description: "declared and not used" is technically correct, but might confuse the user. Switching "and" to "but" will hopefully create the contrast for the users: they did one thing (declaration), but not the other --- actually using the variable.

2019-05-16compiler: improve escape analysis on interface conversionsCherry Zhang1-1/+4
If an interface does not escape, it doesn't need a heap allocation to hold the data (for non-direct interface type). This CL improves the escape analysis to track interface conversions, and reduces these allocations. Implicit interface conversions were mostly added late in the compilation pipeline, after the escape analysis. For the escape analysis to see them, we move the introduction of these conversions earlier, right before the escape analysis. Now that the compiler can generate interface conversions inlined, gcc/testsuite/go.test/test/nilptr2.go needs to be adjusted as in golang.org/cl/176579, so the use function does an actual use.
