Subject: [PATCH] Change more x64 size checks to not apply to x32.
X-Git-Tag: archive/raspbian/1.59.0+dfsg1-1_deb11u3+rpi1~1^2^2^2^2~36
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=17c3f2fdc7e2552f96179b415d57b9f8b3c0426d;p=rustc-mozilla.git

[PATCH] Change more x64 size checks to not apply to x32.

Commit 95e096d6 changed a bunch of size checks already, but more have
been added, so this fixes the new ones the same way: the various size
checks that are conditional on target_arch = "x86_64" were not intended
to apply to x86_64-unknown-linux-gnux32, so add
target_pointer_width = "64" to the conditions.
