Bug ID: 16275
Summary: x86-64 dynamic linker should preserve bound registers
Product: glibc
Version: 2.19
Status: NEW
Severity: normal
Priority: P2
Component: dynamic-link
Assignee: unassigned at sourceware dot org
Reporter: hjl.tools at gmail dot com
Intel MPX uses bound registers for bound parameter
passing. Since legacy branches will destroy bound
registers, ld.so should preserve bound registers.
