6829 identifier character. Take no arguments.
6830 (cpp_reader_init): Call initialize_char_syntax with no
6832 (cpp_start_read): Don't call initialize_char_syntax again.

6834 opts->dollars_in_ident.
6836 * cpplib.h (struct cpp_reader): Replace void *data element by

6874 hardcoded MASK, which is safe since this is the source
6877 * cppexp.c: Bring over changes to cpp_parse_escape from cccp.c
6878 to handle wide character constants in #if directives. The
6879 function now returns a HOST_WIDE_INT, and takes a third
6880 argument which is a binary mask for all legal values (0x00ff
6881 for 8-bit `char', 0xffff for 16-bit `wchar_t', etc.) Define
6882 MAX_CHAR_TYPE_MASK and MAX_WCHAR_TYPE_MASK. Change callers of
6883 cpp_parse_escape to match. [Fixes c-torture/execute/widechar-1.c]

7688 The strategy we now use is to pre allocate the top_elt along
7689 with the EH context so that each thread has its own top_elt.
7690 This is necessary as the dynamic cleanup chain is used on the
7691 top element of the stack and each thread MUST have its own.

13809 (gen_compare_reg): Remove TARGET_V8PLUS cmpdi_v8plus emission.
13810 (legitimize_pic_address): Emit movsi_{high,lo_sum}_pic instead of
13811 old pic_{sethi,lo_sum}_si patterns.
13812 (mem_min_alignment): New generic function to replace
13813 mem_aligned_8, which uses REGNO_POINTER_ALIGN information when
13814 available and can test for arbitrary alignments. All callers

13853 addresses into a register properly.
13854 (EXTRA_CONSTRAINT): Document more accurately, remove Q case as it
13856 (GO_IF_LEGITIMATE_ADDRESS): Allow TFmode for LO_SUM on v9 since fp
