21 These are patches to the main gcc source distribution for specific releases. | |
22 The last number after the dash is a patch level for the specific patch. | |
23 These are different to the official gcc6809 releases in the following ways. | |
24 First, all the source for as-6809 is removed. Also, the special "helper" | |
25 makefile and directory is removed. Also, as of this writing, the | |
26 distribution side for gcc6809 has been down for months and the latest | |
27 release was for gcc 4.3.4 which does not build on 64 bit linux. | |
