| [Polly] Remove autotools build systems from Externals. NFC. Building a source distribution using autotools adds GPL-licenced files into the the sources. Although redistribution of theses files is explicitly allowed with an exception, these are not used by Polly which uses a CMake replacement. Use the direct source checkout instead (replacing the output of 'make dist'). Some m4 scripts with the same licence are also included in isl/ppcg repository. Removing them renders the autotools-based build scipts inoperable, so remove the autotools build system altogether. | 4 年前 |
