re PR c/7054 (#pragma pack handled incorrectly)
PR c/7054
* defaults.h (TARGET_DEFAULT_PACK_STRUCT): Provide default.
* tree.h (initial_max_fld_align): Declare
* stor-layout.c (initial_max_fld_align): Define and initialize.
(maximum_field_alignment): Initialize to the same value.
* common.opt: Add -fpack-struct= variant of switch.
* opts.c: Handle -fpack-struct= variant of switch.
* c-pragma.c: Change #pragma pack() handling so that it becomes
compatible to other compilers: accept individual 'push' argument,
make final pop restore (command line) default, correct interaction
of push/pop and sole specification of a new alignment (so that the
sequence #pragma pack(push) - #pragma pack(<n>) becomes identical
to #pragma pack(push, <n>).
* doc/extend.texi: New node "Structure-Packing Pragmas" under
"Pragmas", describing #pragma pack.
* doc/invoke.texi: Document -fpack-struct=<n> variant of switch.
* doc/tm.texi: Adjust description for HANDLE_PRAGMA_PACK_PUSH_POP.
Document new TARGET_DEFAULT_PACK_STRUCT.
testsuite:
* gcc.dg/pack-test-2.c: Adjust to permit and check #pragma pack(push).
* gcc.dg/c99-flex-array-4.c: Add -fpack-struct=8 to provide a
deterministic starting point for the alignment of structure fields.
* gcc.dg/Wpadded.c: Dito.
* g++.dg/abi/vbase10.C: Dito.
