lib9: provide alterantive implementation of ldexp and frexp 2015-02-06T05:40:28+00:00 Shenghou Ma minux@golang.org 2014-12-26T05:08:51+00:00 db0d3892e0f3b246475c473685249427f86e3a56 Libc on Darwin/ARM has a buggy implementation of ldexp and frexp that could not handle denormal numbers. Also disable VFP runfast (flush-to-zero) mode so that the gc compiler can correctly handle denormal constants used in math and strconv tests.

lib9: build tokenize on Plan 9 2015-01-21T23:27:01+00:00 David du Colombier 0intro@gmail.com 2015-01-21T23:25:08+00:00 98d914201b98a854c7d172837d19ff7d0096b405 The build was broken on Plan 9 after the CL 2994, because of the use of getfields in src/liblink/go.c. This happened when building 8l, because getfield was part of lib9 and tokenize was part of the Plan 9 libc. However, both getfields and tokenize depend on utfrune, causing an incompatibility.

lib9, cmd/ld: fixes for cross-linking on a Windows host 2014-09-19T00:27:26+00:00 Ian Lance Taylor iant@golang.org 2014-09-19T00:27:26+00:00 5a40b568d023922e735ddc21f3b4a30d52197b7a This fixes a couple of problems that occur when the linker removes its temporary directory on Windows. The linker only creates and removes a temporary directory when doing external linking. Windows does not yet support external linking. Therefore, these problems are only seen when using a cross-compiler hosted on Windows. In lib9, FindFirstFileW returns just the file name, not the full path name. Don't assume that we will find a slash. Changed the code to work either way just in case. In ld, Windows requires that files be closed before they are removed, so close the output file before we might try to remove it. Fixes #8723.
