Disconnect3d	66d5d6cc51	Fix early arch detection & the 'Cannot find ELF base!' warning ... Before this commit, when we did `gdb /bin/ls` and then `entry`, we could see a "Cannot find ELF base!" warning. This occured, because the `pwndbg.arch.ptrmask` was incorrectly set and then the `find_elf_magic` was using the `pwndbg.arch.ptrmask` which was 0xffFFffFF and made an early return. As a result of this early return, the "Cannot find ELF base!" warning was emitted. The reason for incorrect early arch detection is that we used the `gdb.newest_frame().architecture().name()` API while the binary was not using in here: ```python @pwndbg.events.start @pwndbg.events.stop @pwndbg.events.new_objfile def update(): m = sys.modules[__name__] try: m.current = fix_arch(gdb.newest_frame().architecture().name()) except Exception: return m.ptrsize = pwndbg.typeinfo.ptrsize m.ptrmask = (1 << 8*pwndbg.typeinfo.ptrsize)-1 ``` And if the binary was not running, we just returned early and did not set `pwndbg.arch.ptrsize` and `pwndbg.arch.ptrmask` at all, leaving them at their default values. Now, those values were often eventually fixed, but this occured by chance as the `new_objfile` was executed! Anyway, starting from this commit, we will detect the arch from `gdb.newest_frame().architecture().name()` only if the process is running and if it is not, we will fallback to the `show architecture` GDB command and parse it, hoping we detect the arch properly. In case we don't, or, we don't support the given arch, we raise a `RuntimeError` currently. Also, as a side note: the `find_elf_magic` from `elf.py` can be optimized to instead of doing 4kB steps over pages, to just look at the begining of a page. Otherwise, if this doesn't work, we are most likely on a target that may not have an ELF magic/header at all, so we shouldn't bother about it. This fix is done in the next commit.	4 years ago

jaseg	011752a1ff	Add initial support for ARM Cortex-M baremetal debugging (#264) (#654) ... This commit adds support for xPSR to be used instead of cPSR on Cortex-M ARMs. Prior to this commit, pwndbg would crash when attached to a Cortex-M core. This commit adds a new internal arch "armcm" to describe Cortex-M ARMs. Closes #542, fixes the second issue in #264	7 years ago
