From: Tom de Vries Date: Thu, 9 May 2019 10:24:38 +0000 (+0200) Subject: [gdb/testsuite] Fix gdb.arch/amd64-tailcall-self.S X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=63b667adb4a915f13ec3ace77af4b9cbd76bceac;p=binutils-gdb.git [gdb/testsuite] Fix gdb.arch/amd64-tailcall-self.S The test-case gdb.arch/amd64-tailcall-self.exp fails here: ... if ![runto b] { return -1 } ... like: ... (gdb) file build/gdb/testsuite/outputs/gdb.arch/amd64-tailcall-self/\ amd64-tailcall-self Reading symbols from build/gdb/testsuite/outputs/gdb.arch/\ amd64-tailcall-self/amd64-tailcall-self... Dwarf Error: Cannot find DIE at 0x1f5 referenced from DIE at 0x107 [in \ module build/gdb/testsuite/outputs/gdb.arch/amd64-tailcall-self/\ amd64-tailcall-self] ... The problem is that in amd64-tailcall-self.S, CU-relative references are assigned .debug_info section relative values. [ This is similar to the problem fixed by "Fix gdb.arch/amd64-entry-value-paramref.S". ] Fix this by assigning CU-relative references instead.
