* sys: Automated cleanup of cdefs and other formattingWarner Losh2023-11-271-1/+0

* Determine the operand/address size of %cs in a new functionBruce Evans2016-09-251-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | db_segsize(). Use db_segsize() to set the default operand/address size for disassembling. Allow overriding this with the "alternate" display format /I. The API of db_disasm() should be debooleanized to pass a more general request (amd64 needs overrides to sizes of 16, 32, and 64, but this commit doesn't implement anything for amd64 since much larger changes are needed to restore the amd64 disassmbler's support for non-default sizes). Fix db_print_loc_and_inst() to ask for the normal format and not the alternate in normal operation. This is most useful for vm86 mode, but also works for 16-bit protected mode. Use db_segsize() to avoid trying to print a garbage stack trace if %cs is 16 bits. Print something like the stack trace termination message for a trap boundary instead. Document that the alternate format is now useful on i386. Notes: svn path=/head/; revision=306311

* Revert r298938: Change x/a to work similar to gdb.Pedro F. Giffuni2016-05-061-13/+10

* Enhance the ddb examine (x) command.Pedro F. Giffuni2016-05-021-10/+13
| | | | | | | | | | | | | | | | | | | | * Change x/a to work similar to gdb. The content of the memory is treated as an address, printed symbolically and the address is advanced. This way you can x/a <stack_address> and then just hit return a bunch of times to locate useful data on the stack. * Add x/p. The content of the memory is treated as an address and printed as hex. This is based on the similar commit from DragonFlyBSD without the cosmetic changes.

* Don't return undefined symbols to a DDB symbol lookup.Mark Johnston2015-07-211-2/+6
| | | | | | | | | | | | | | | | | | | Undefined symbols have a value of zero, so it makes no sense to return such a symbol when performing a lookup by value. This occurs for example when unwinding the stack after calling a NULL function pointer, and we confusingly report the faulting function as uart_sab82532_class() on amd64. Convert db_print_loc_and_inst() to only attempt disassembly if we managed to find a symbol corresponding to the IP. Otherwise we may fault and re-enter the debugger.

| | | | | | | | | | | | | | | | | | | value at the requested address as a symbol. For example, "ex /S aio_swake" prints the name of the function currently registered in via aio_swake hook. The change as committed differs slightly from the patch in the PR, as I force the size of the retrieved value (and the automatic address increment) to be sizeof(void *). This seems to provide the most useful auto-increment behavior, and defaults using the default size (4), which is not sizeof(void *) on 64-bit platforms.

The fix is to pass the width of the next output to db_end_line() and not assume there that this width is always 1. Related unfixed bugs: - 1 character is wasted for a space after the last column - suppression of trailing spaces used to limit the misformatting, but seems to have been lost - in db_examine(), the width of the next output is not know and is still assumed to be 1.
