From 41899c04122d85b9ce11715061d03330b1d59175 Mon Sep 17 00:00:00 2001 From: Andrew Cagney Date: Fri, 23 Mar 2001 00:41:02 +0000 Subject: [PATCH] * config/pa/xm-hppah.h (HPPA_COMPILER_BUG): Delete.

I haven't - been able to construct a simple test case. The problem is that - in the second call to SKIP_PROLOGUE below, the compiler somehow - does not realize that the statement val = find_pc_line (...) will - change the values of the fields of val. It extracts the elements - into registers at the top of the block, and does not update the - registers after the call to find_pc_line. You can check this by - inserting a printf at the end of find_pc_line to show what values - it is returning for val.pc and val.end and another printf after - the call to see what values the function actually got (remember, - this is compiling with cc -O, with this patch removed). You can - also examine the assembly listing: search for the second call to - skip_prologue; the LDO statement before the next call to - find_pc_line loads the address of the structure which - find_pc_line will return; if there is a LDW just before the LDO, - which fetches an element of the structure, then the compiler - still has the bug. - - Setting val to volatile avoids the problem.
