PR c++/20505 * dwarf2out.c (rtl_for_decl_init): New function. (rtl_for_decl_location): Extracted from here. (tree_add_const_value_attribute): Call rtl_for_decl_init and add_const_value_attribute.

--- Additional Comments From wilson at gcc dot gnu dot org 2005-04-01 04:04 --- Fixed on mainline. Still needs to be fixed on the gcc-4.0 branch, which I assume Nathan is doing. I had to back off a bit from my earlier plans. Aggregate types and constructor initializers pose complications that don't appear to be worth fixing, so I only handle integral types, scalar real types, and STRING_CST. I commonized the code in rtl_for_decl_location and tree_add_const_value_attribute so that they both work the same. The testcase by the way isn't portable. It requires that int and pointer be the same size. I had to do s/int/long to make it work on my ia64 and x86_64 systems. But still that assumes long and pointers are the same size which is not true for all ABIs supported by all targets. This is why I didn't already add the testcase to the testsuite on mainline. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20505

--- Additional Comments From mmitchel at gcc dot gnu dot org 2005-03-24 17:48 --- This is a missed-optimization bug as well, in that the initialization expression should be simplified to a constant. -- What|Removed |Added Keywords||missed-optimization http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20505

--- Additional Comments From nathan at gcc dot gnu dot org 2005-03-24 18:58 --- actually, it'd be a miscompile if it had a dynamic initializer (because the std says such a thing *must* be static initialized). Fortunately the assembly is correct (which is kind of bizarre) .type _ZN1b1dE, @object .size _ZN1b1dE, 4 _ZN1b1dE: .long 8 -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20505
