Bug ID: 69747
Summary: c6x cross-compiler fails with "Error: inconsistent
uses of .cfi_sections"
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: dhowells at redhat dot com
Target Milestone: ---
When building both gcc-5.3.1 and gcc-6 for c6x, the builds fail when
configuring libgcc with the following error:
/tmp/cc6wIVaX.s: Assembler messages:
/tmp/cc6wIVaX.s:12: Error: inconsistent uses of .cfi_sections
This can be tested in the build tree with:
echo 'int main() { return 0; }' | ./gcc/xgcc -x c -c -g - -B ./gcc
-fexceptions
The gcc being built is the following:
%global DATE 20151207
%global SVNREV 231358
%global gcc_version 5.3.1
gcc is configured as follows:
CC=gcc \
CXX=g++ \
