Bug ID: 90375
Summary: Environment variables not listed in ENVIRONMENT
section of man page
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Keywords: documentation
Severity: minor
Priority: P3
Component: other
Assignee: unassigned at gcc dot gnu.org
Reporter: redi at gcc dot gnu.org
Target Milestone: ---
The following env vars are documented as affecting GCC's behaviour, but are not
listed in the ENVIRONMENT section of the gcc(1) man page:
GCC_COLORS (for -fdiagnostics-color)
COLUMNS (for -fno-diagnostics-show-caret)
MAKE (for -flto=n)
ASAN_OPTIONS
TSAN_OPTIONS
LSAN_OPTIONS
VTV_LOGS_DIR (for -fvtv-debug)
PATH (for finding subprograms when -Bprefix and the standard locations don't
have them)
-M mentions "or use an environment variable like DEPENDENCIES_OUTPUT" which
isn't very clear if that actually gets used by GCC or is just an example. I
suggest saying "or use one of the environment variables DEPENDENCIES_OUTPUT or
SUNPRO_DEPENDENCIES" instead.
There's also "The runtime library behavior can be influenced using various
CHKP_RT_* environment variables. See
<https://gcc.gnu.org/wiki/Intel%20MPX%20support%20in%20the%20GCC%20compiler>
for more details."
