Re: [Patch, fortran] PR65792 unitialized structure constructor array subcomponent

Dominique reported that the trunk patch breaks class_19.f90 when applied together with Andre's PR59678 fix. It appears to me that even without Andre's patch, the code generated is wrong, and I don't see any easy fix. Thus I'm withdrawing trunk's patch, and propose the backport patch also for trunk.

[PATCH] PRs target/65846/65886: Improve copy reloc in PIE

Normally, with PIE, GCC accesses globals that are extern to the module using GOT. This is two instructions, one to get the address of the global from GOT and the other to get the value. Examples: --- extern int a_glob; int main () { return a_glob; } --- With PIE, the generated code accesses g

Dear Andre, Sorry, Mikael's patch for pr65792! Also, your patch for PR59678 had better be applied to 5.1 and to 4.9, since bug generates such grossly wrong code. Cheers Paul On 25 April 2015 at 16:42, Paul Richard Thomas wrote: > Dear Andre, > > The patch is OK with three changes: > (i) Put t

Re: [Patch, fortran, pr59678, v1] -- [F03] Segfault on equalizing variables of a complex derived type

Dear Andre, The patch is OK with three changes: (i) Put the PR line in the testsuite ChangeLog; (ii) Put the dg-do header information in the testcase, together with lines to say which PR it fixes and who the contributor is; and (iii) Add the testcase for PR65841 since your patch for pr65792 breaks

[PATCH][PR65818][bootstrap,hppa] Return side-effect free result in gimplify_va_arg_internal

Hi, this patch fixes PR65818, and hppa bootstrap. When compiling gcc/libiberty/vprintf-support.c, the following va_arg is compiled: ... (void) __builtin_va_arg(ap, double); ... This results in the following ifn_va_arg at gimple level, with a NULL_TREE lhs: ... VA_ARG (&ap, 0B); ... We star

[Patch, Fortran] Simplify lbound

Hello world, this is a simplification for calculating the lboud of assumed-shape arrays - it is usually one, or whatever the user specified as lower bound (if constant). The surprising thing was that the current code generated for the array descriptor for subroutine foo(a, b, n, m) integer
