* Stated the compiler and coverage requirements instead of citing a file no contributor can open
Seven comments across five files cited a maintainer-local document as the
source for two project requirements: that GCC 14 on Linux is the default
compiler, and that the coverage target is 100%. That document is not part of
this repository and is not published anywhere, so the citation gave a reader
nothing to follow -- it named a source they cannot open, in place of simply
stating the requirement.
Both requirements are real and both stay. Only the pointer goes: each comment
now states the requirement on its own terms, which is what the surrounding
prose was already doing everywhere else.
cmake/cortex_r52.cmake the pinned reference toolchain
scripts/check_gcc.sh why the script exists
.github/workflows/gcc_check.yml why the workflow exists, and the
GCC_VERSION pin
.github/workflows/r52_fvp.yml the GCC_VERSION pin
.github/workflows/regression_template.yml the coverage floor, twice
Comments only; no behaviour changes. Two paragraphs are rewrapped where the
shorter text left a ragged line. Verified that scripts/check_gcc.sh still
parses and prints its help from the header range it slices, and that
cmake/cortex_r52.cmake still configures the Cortex-R52 build.

* Said who the pinned toolchain default in the CMake toolchain files serves
Both cmake/cortex_r52.cmake and cmake/cortex_m52.cmake default
ARM_TOOLCHAIN_PATH to a toolchains directory under the user's home, guarded by
an EXISTS check. Nothing said whether CI relies on that, and the natural
reading is that it does.
It does not. The three workflows that install a toolchain unpack it into the
workspace and cache it there, and r52_fvp.yml puts that directory on PATH
before configuring; scripts/check_gcc.sh passes -DARM_TOOLCHAIN_PATH at each of
its three CMake call sites. On a runner the guarded directory is absent, the
EXISTS check falls through, and the compiler comes from PATH. The default only
ever fires on a developer machine, where it is what makes a no-flag build work.
Both comments now say that, so the default is not mistaken for a CI dependency
and not removed as dead code. cortex_r52.cmake carries the explanation and
cortex_m52.cmake refers to it, matching the cross-reference already there.
The r52 comment also claimed absolute paths mean "the build does not depend on
PATH ordering", which is only true where the pinned directory exists -- in CI
the build depends on PATH and nothing else. Qualified accordingly.
Comments only; no behaviour changes. Verified that both toolchain files still
configure, and that the fall-through is real: with HOME pointed at a directory
holding no toolchains, cortex_r52.cmake configures against the arm-none-eabi-gcc
found on PATH.
