re PR rtl-optimization/6627 (-fno-align-functions regression from 2.95)
PR optimization/6627
* toplev.c (force_align_functions_log): New global variable.
* flags.h (force_align_functions_log): Add extern prototype.
* varasm.c (assemble_start_function): Use it to force minimum
function alignment.
* config/i386/i386.h (FUNCTION_BOUNDARY): Set the correct
minimum function alignment to one byte.
(TARGET_PTRMEMFUNC_VBIT_LOCATION): Store the virtual bit in
the least significant bit of vtable member function pointers.
* tree.h (enum ptrmemfunc_vbit_where_t): Move definition to
here from cp/cp-tree.h.
* cp/cp-tree.h (enum ptrmemfunc_vbit_where_t): Delete definition
from here, and move it to tree.h.
* cp/decl.c (cxx_init_decl_processing): If storing the vbit
in function pointers, ensure that force_align_functions_log
is atleast one.
* java/lang.c (java_init): If storing the vbit in function
pointers, ensure that force_align_functions_log is atleast
one to aid compatability with g++ vtables.
