6834 * i386/bsd.h (ASM_FILE_START): Don't use dump_base_name, it is
6835 wrong and should only be used for dump related things, not
6836 debugging information, instead main_input_filename should be used.
6837 Also, reuse output_file_directive if possible.
6838 * i386/aix386ng.h (ASM_FILE_START): Likewise.

6877 identifier character. Take no arguments.
6878 (cpp_reader_init): Call initialize_char_syntax with no
6880 (cpp_start_read): Don't call initialize_char_syntax again.

6882 opts->dollars_in_ident.
6884 * cpplib.h (struct cpp_reader): Replace void *data element by

6922 hardcoded MASK, which is safe since this is the source
6925 * cppexp.c: Bring over changes to cpp_parse_escape from cccp.c
6926 to handle wide character constants in #if directives. The
6927 function now returns a HOST_WIDE_INT, and takes a third
6928 argument which is a binary mask for all legal values (0x00ff
6929 for 8-bit `char', 0xffff for 16-bit `wchar_t', etc.) Define
6930 MAX_CHAR_TYPE_MASK and MAX_WCHAR_TYPE_MASK. Change callers of
6931 cpp_parse_escape to match. [Fixes c-torture/execute/widechar-1.c]

7623 out the definition. It was being called incorrectly and at
7624 the wrong times. Until a VMSie can look at this, it's better

7736 The strategy we now use is to pre allocate the top_elt along
7737 with the EH context so that each thread has its own top_elt.
7738 This is necessary as the dynamic cleanup chain is used on the
7739 top element of the stack and each thread MUST have its own.

13902 (EXTRA_CONSTRAINT): Document more accurately, remove Q case as it
13904 (GO_IF_LEGITIMATE_ADDRESS): Allow TFmode for LO_SUM on v9 since fp
