Bug #: 54723
Summary: test gcc.target/arm/div64-unwinding.c fails for
GNU/Linux target
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: ja...@gcc.gnu.org
Target: arm-none-linux-gnueabi
Test gcc.target/arm/div64-unwinding.c checks that performing a 64-bit division
does not pull in the unwinder. When Julian Brown added the test he mentioned
that it was for use with bare-metal targets, but the test is not restricted to
them. When asked about it recently he said "Actually the mechanism through
which the test fails for Linux/glibc is unknown: it might be worth trying to
figure out what causes the unwinder to be pulled into the binary for Linux
toolchains. Or it might not..."
I plan to XFAIL the test for GNU/Linux targets, so this PR provides a handy
place to record additional thoughts about the failure.
