# webrtc::XErrorTrap (used by the X11 desktop-capture sources enabled for ia64
# in hotfix-ia64-webrtc-gn.patch) is provided by Mozilla's libwebrtc override
# modules/desktop_capture/linux/x11/x_error_trap.cc. Unlike the GN-generated
# moz.build files, dom/media/webrtc/libwebrtc_overrides/moz.build is hand-written
# and gates that source on an explicit TARGET_CPU allow-list that omits ia64, so
# XErrorTrap's ctor/dtor/GetLastErrorAndDisable are left undefined at libxul link
# time. ia64 is a 64-bit little-endian X11 target; treat it like ppc64 here.
