From 80150dc7ac41e767d857905702bf4b57eb1c0029 Mon Sep 17 00:00:00 2001 From: Tom de Vries Date: Fri, 16 Aug 2024 14:22:46 +0200 Subject: [PATCH 11/46] [gdb/testsuite] Fix gdb.dwarf2/dw2-fixed-point.exp on arm-linux With test-case gdb.dwarf2/dw2-fixed-point.exp on arm-linux I run into: ... (gdb) PASS: gdb.dwarf2/dw2-fixed-point.exp: set lang ada print pck.fp1_var^M $1 = 0.3125^M (gdb) FAIL: gdb.dwarf2/dw2-fixed-point.exp: print pck.fp1_var ... The problem is that the thumb prologue analyzer overshoot, setting the breakpoint for main after line 49: ... 46 int 47 main (void) 48 { 49 pck__fp1_var++; ... and consequently we see the value of pck.fp1_var after line 49 instead of before line 49. This is PR tdep/31981. Work around this by removing line 49 and all similar subsequent lines, which turn out to be dead code.
