------- Comment #7 from rob1weld at aol dot com 2009-04-05 17:31 ------- I can build gcc with the Ada Language using Trunk revision 145337 but the changes made in the next revision cause the build to fail.
The Changelog indicates Richard Guenther made the changes on 2009-03-31. There were no changes made to Ada, only to the middle-end (AFAIK). # ./contrib/gcc_update -r 145338 Updating SVN tree U gcc/java/java-gimplify.c U gcc/java/ChangeLog U gcc/tree.h U gcc/ChangeLog A gcc/testsuite/gcc.dg/tree-ssa/pr23401.c A gcc/testsuite/gcc.dg/tree-ssa/pr27810.c U gcc/testsuite/ChangeLog U gcc/tree-eh.c U gcc/gimplify.c U gcc/tree-ssa-pre.c U gcc/tree-mudflap.c U gcc/gimple.c U gcc/gimple.h U gcc/tree-cfg.c Updated to revision 145338. I do not know the middle-end well enough to tamper with it. I would appreciate if the remainder of this work could be undertaken by someone else. I do not think that this is entirely Operating System specific, others may be affected too. # gcc/xgcc -v Using built-in specs.
