2015-08-27More fallout from "Allow symbol and label names to be enclosed in double quotes"Alan Modra1-4/+3
Some of the TC_START_LABEL implementations need to adjust the end of the symbol, when a colon doesn't mean a label definition. That means they need access to nul_char both the restore the NUL location (it may be a quote rather than a colon) and to store the new nul_char. Others need adjusting to step over a potential trailing quote. PR gas/18581 * config/tc-aarch64.h (TC_START_LABEL): Redefine. * config/tc-arm.c (tc_start_label_without_colon): Delete params.

2015-01-12gas: allow labeling of CFI instructionsJan Beulich1-1/+1
When runtime patching code (like e.g. done by the Linux kernel) there may be cases where the set of stack frame alterations differs between unpatched and patched code. Consequently the corresponding unwind data needs patching too. Locating the right places within an FDE, however, is rather cumbersome without a way to insert labels in the resulting section. Hence this patch introduces a new directive, .cfi_label. Note that with the way CFI data gets emitted currently (at the end of the assembly process) this can't support local FB- and dollar-labels. gas/ 2015-01-12 Jan Beulich <jbeulich@suse.com> * gas/dw2gencfi.c (cfi_add_label, dot_cfi_label): New.

The construct being added to the cond.s test case otherwise triggered both the "missing closing ..." and the "stray ..." (twice) warnings in _find_end_of_line().

A number of targets pass extra information from TC_PARSE_CONS_EXPRESSION to TC_CONS_FIX_NEW via static variables.
