Source: gcc-7 Version: 7.2.0-18 Severity: normal Tags: patch User: [email protected] Usertags: ia64 Hi! Like with gcc-6 in #885428, we need to patch src:gcc-7 to use the internal libunwind library when cross-building for a ia64 target. The attached patch makes the necessary modifications which have been verified to work in rebootstrap. A second patch by James Clarke is necessary to modify some linker flags for building the internal libunwind. I will file a second bug report for that. Adrian -- .''`.
