compiler: add slice initializers to the GC root list

    As of https://golang.org/cl/32917 we can put slice initializers in the
    .data section.  The program can still change the values in those
    slices.  That means that if the slice elements can contain pointers,
    we need to register the entire initializer as a GC root.

    This would be straightforward except that we only have a Bexpression
    for the slice initializer, not an Expression.  So introduce a
    Backend_expression type that wraps a Bexpression as an Expression.

8 years agoruntime: print C functions in traceback
Ian Lance Taylor [Wed, 30 Nov 2016 20:28:28 +0000 (20:28 +0000)]
runtime: print C functions in traceback

    Since gccgo can trace back through C code as easily as Go code, we
    should print C functions in the traceback.

    This worked before https://golang.org/cl/31230 for a dumb reason.  The
    default value for runtime.traceback_cache was, and is, 2 << 2, meaning
    to print all functions.  The old C code for runtime_parsedebugvars
    would return immediately and do nothing if the environment variable
    GODEBUG was not set (if GODEBUG was set it would later call
    setTraceback.  The new Go code for runtime.parsedebugvars does not
    return immediately if GODEBUG is not set, and always calls
    setTraceback.  Either way, if GOTRACEBACK is not set, setTraceback
    would set traceback_cache to 1 << 2, meaning to only print non-runtime
    functions and having the effect of not printing plain C functions.

    Keep the current handling of GODEBUG/GOTRACEBACK, which matches the gc
    library, but add an extra check to print C functions by default.

generate substring locations in a .i file where the underlying .c file
has changed since the .i file was generated.

This can't work, so it seems safest for the on-demand substring
locations to be unavailable for such files, falling back to
"whole string" locations for such cases.

gcc/ChangeLog:
PR preprocessor/78569
* input.c (get_substring_ranges_for_loc): Fail gracefully if
line directives were present.

gcc/testsuite/ChangeLog:
PR preprocessor/78569
* gcc.dg/format/pr78569.c: New test case.
