This is heavily based on the oe-core master commit with the same subject, but includes a backport of upstream's fix for the fallthrough warnings rebased to 0.166 (the oe-core patch which targeted 0.168 did not apply), a rebase of the format-truncation patch, and a backport of the upstream format-length patch. Info from OE-Core master patch follows: From OE-Core rev: aaf4c4f3d09ac3897205417eb15e19d54e0c0d05 From: Joshua Lock <joshua.g.lock@intel.com> Backport a fix from upstream for a -Wformat-truncation=2 warning and implement a simple fix for a -Wimplicit-fallthrough warning.

Subject: [PATCH 1/2] libasm: Fix one GCC7 -Wformat-truncation=2 warning.
|
|
|
|
Make sure that if we have really lots of labels the tempsym doesn't get
|
|
truncated because it is too small to hold the whole name.
|
|
|
|
This doesn't enable -Wformat-truncation=2 or fix other "issues" pointed
|
|
out by enabling this warning because there are currently some issues
|
|
with it. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=79448
