Add a very hackish /proc/PID/stack. It walks the stack and identifies anything that looks like a kernel symbol. This could be a lot more sophisticated. 2018-10-26 20:32:35 +00:00			`#!/bin/sh`

Kernel: Use the toolchain's `nm` in mkmap.sh By using the binary from our build of binutils, we can be sure that `nm` supports demangling symbols, so we can avoid spawning a separate `c++filt` process. 2021-12-30 16:17:29 +00:00			`NM="${NM:-nm}"`

Kernel: Embed the right symbol count into the kernel.map file on macOS On macOS the wc tool prefixes its output with a bunch of spaces which resulted in us incorrectly using "00000000" as the symbol count. Fixes #9080. 2021-07-29 06:42:09 +00:00			`printf "%08x\n" "$(wc -l "$tmp" \| awk '{print $1}')" > kernel.map`

Meta: Fix shellcheck warnings in various scripts Warnings fixed: * SC2086: Double quote to prevent globbing and word splitting. * SC2006: Use $(...) notation instead of legacy backticked `...` * SC2039: In POSIX sh, echo flags are undefined * SC2209: Use var=$(command) to assign output (or quote to assign string) * SC2164: Use 'cd ... \|\| exit' or 'cd ... \|\| return' in case cd fails * SC2166: Prefer [ p ] && [ q ] as [ p -a q ] is not well defined. * SC2034: i appears unused. Verify use (or export if used externally) * SC2046: Quote this to prevent word splitting. * SC2236: Use -z instead of ! -n. There are still a lot of warnings in Kernel/run about: - SC2086: Double quote to prevent globbing and word splitting. However, splitting on space is intentional in this case, and not trivial to change. Therefore ignore the warning for now - but we should fix this in the future. 2020-02-10 06:09:08 +00:00			`rm -f "$tmp"`
