2021-02-02pw_cpu_exception_cortex_m: Move armv7m->cortex_mArmando Montanez
Moves the armv7m implementation of pw_cpu_exception to pw_cpu_exception_cortex_m since much of the logic can be shared between ARMv8-M and ARMv7-M. Symbol names are also updated to reflect current naming style for extern "C" symbols. Old names will be removed in pwrev/31060. Warning, symbol renames are breaking! pw_CpuExceptionEntry -> pw_cpu_exception_Entry pw_CpuExceptionDefaultHandler -> pw_cpu_exception_DefaultHandler Change-Id: I7ab99ac7637c436ba959d7546043090c66fe4215 Reviewed-on: https://pigweed-review.googlesource.com/c/pigweed/pigweed/+/30922 Commit-Queue: Auto-Submit <auto-submit@pigweed.google.com.iam.gserviceaccount.com> Reviewed-by: Ewout van Bekkum <ewout@google.com> Pigweed-Auto-Submit: Armando Montanez <amontanez@google.com>

2020-10-01docs: Make labels consistent; remove boilerplateWyatt Hepler
- Update labels so they use consistent naming. Instead of the copy-and-pasted `chapter` prefix, name labels with a prefix consistent with what they point to: - "module-" for module - "target-" for targets - "docs-" for general documentation - Remove the unnecessary highlight and default-domain directives. Neither is necessary since the Pigweed docs always specify the language in code snippets and other directives.
