Fix initializing members multiple times

2016-12-15T16:49:53Z

When intializing members where the initializer needs relocations and the member is initialized multiple times we can't allow that to lead to multiple relocations to the same place. The last one must win.

struct-init: Copy relocs for compound literals

2016-12-15T16:47:12Z

When copying the content of compound literals we must include relocations as well.

struct-init: Support range inits for local vars

2016-12-15T16:47:09Z

Implement missing support for range init for local variables.

struct-init: Allow member initialization from qualified lvalues

2016-12-15T16:47:09Z

See testcase.

struct-init: Correctly parse unnamed member initializers

2016-12-15T16:47:09Z

For union U { struct {int a,b}; int c; }; union U u = {{ 1, 2, }}; The unnamed first member of union U needs to actually exist in the structure so initializer parsing isn't confused about the double braces. That means also the a and b members must be part of _that_, not of union U directly. Which in turn means we need to do a bit more work for field lookup. See the testcase extension for more things that need to work.

struct-init: Cleanup

2016-12-15T16:47:09Z

Remove dead code and variables. Properly check for unions when skipping fields in initializers. Make tests2/*.expect depend on the .c files so they are automatically rebuilt when the latter change.

struct-init: Implement initializing subaggregates

2016-12-15T16:47:09Z

E.g. "struct { struct S s; int a;} = { others, 42 };" if 'others' is also a 'struct S'. Also when the value is a compound literal. See added testcases.
