Bug ID: 27221
Summary: Commit 058430b4a1ed7441dfc2e167bfdb9dc89ea9a209
introduces warnings while assembling the Linux kernel
Product: binutils
Version: 2.37 (HEAD)
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: gas
Assignee: unassigned at sourceware dot org
Reporter: natechancellor at gmail dot com
Target Milestone: ---
When I build some Linux kernel targets with tip of tree binutils, I see a
series of warnings like:
Warning: dwarf line number information for ... ignored
It looks like this was introduced by 058430b4a1ed7441dfc2e167bfdb9dc89ea9a209
according to my bisect. This is quite noisy in my builds as I see it with a
variety of configurations and architectures. For example, with the attached
cache-v7.s from the arch/arm directory:
$ as-new -EL -mfloat-abi=soft -march=armv7-a -mfpu=vfp -mno-warn-deprecated
-gdwarf-2 -o /dev/null cache-v7.s
arch/arm/mm/cache-v7.S:84: Warning: dwarf line number information for
.alt.smp.init ignored
arch/arm/mm/cache-v7.S:100: Warning: dwarf line number information for
.alt.smp.init ignored
arch/arm/mm/cache-v7.S:105: Warning:
dwarf line number information for .alt.smp.init ignored
arch/arm/mm/cache-v7.S:200: Warning: dwarf line number information for
.alt.smp.init ignored
arch/arm/mm/cache-v7.S:218: Warning:
dwarf line number information for .alt.smp.init ignored
arch/arm/mm/cache-v7.S:310: Warning: dwarf line number information for
.alt.smp.init ignored
Is this intentional? If so, what is the fix?
