btrace: add instruction-history /s and fix documentation
Add support for the /s modifier of the "record instruction-history" command. It
behaves exactly like /m and prints disassembled instructions in the order in
which they were recorded with interleaved sources. We accept /s in addition
to /m to align with the "disassemble" command.
The "record instruction-history" modifiers were not documented. Document
all of them.
gdb/
* record.c (get_insn_history_modifiers): Set DISASSEMBLY_SOURCE
instead of DISASSEMBLY_SOURCE_DEPRECATED. Also accept /s.
(_initialize_record): Document the /s modifier.
* NEWS: Announce record instruction-history's new /s modifier.
doc/
* gdb.texinfo (Process Record and Replay): Document "record
instruction-history" modifiers.
