Bug ID: 124320
Summary: FAIL: gcc.dg/lto/toplevel-extended-asm-1
c_lto_toplevel-extended-asm-1_0.o-c_lto_toplevel-exten
ded-asm-1_1.o link, -O2 -flto -flto-partition=1to1
Product: gcc
Version: 16.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: testsuite
Assignee: unassigned at gcc dot gnu.org
Reporter: azoff at gcc dot gnu.org
Target Milestone: ---
The default mode for an arm-none-eabi toolchain is arm mode and thus, when
testing such a toolchain in thumb mode, the testcase fails as the inline
assembler functions are defaulting back to arm mode and not all targets support
mixing arm and thumb modes.
The test case needs to be updated to support thumb mode and/or duplicated with
a dedicated thumb variant.
