  "message": "[gdb/testsuite] Fix gdb.cp/non-trivial-retval.exp on arm-linux with gcc 13\n\nOn arm-linux, with target board unix/-mthumb, we get:\n...\n(gdb) PASS: gdb.cp/non-trivial-retval.exp: continue to breakpoint: Break here\np f1 (i1, i2)^M\n$1 \u003d {a \u003d -136274256}^M\n(gdb) FAIL: gdb.cp/non-trivial-retval.exp: gdb-command\u003cp f1 (i1, i2)\u003e\n...\n\nThis is not a problem with the inferior call, which works fine:\n...\n(gdb) p f1 (23, 100)\n$3 \u003d {a \u003d 123}\n...\nbut instead it\u0027s a problem with the location information:\n...\n(gdb) p i1\n$1 \u003d -136274356\n(gdb) p i2\n$2 \u003d 100\n...\nwhich tells us to find the value of i1 in (DW_OP_fbreg: -12).\n\nThe test-case passes if we drop -fvar-tracking, in which case the debug info\ntells us to find the value of i1 in (DW_OP_fbreg: -20).\n\nThis is with gcc 13.3.0 on Ubuntu 24.04.  With gcc 14.2.0 on Debian testing,\nthe code is the same, but -fvar-tracking does use the correct\n\u0027(DW_OP_fbreg: -20)\u0027.\n\nThere seems to be some bugfix in -fvar-tracking for gcc 14.\n\nWorkaround the bug by using constants 23 and 100 instead of i1 and i2 when\nusing -fvar-tracking and gcc \u003c 14.\n\nTested on arm-linux.\n\nPR testsuite/32549\nBug: https://sourceware.org/bugzilla/show_bug.cgi?id\u003d32549\n",
