            Bug ID: 94321
           Summary: gdc.dg/pr92216.d FAILs on 32-bit targets
           Product: gcc
           Version: 10.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: d
          Assignee: ibuclaw at gdcproject dot org
          Reporter: ro at gcc dot gnu.org
  Target Milestone: ---
            Target: i386-pc-solaris2.11, sparc-sun-solaris2.11

As originally reported in

https://gcc.gnu.org/pipermail/gcc-patches/2020-March/542177.html

[which didn't get Cc'ed to you due to the abominable header rewriting]:

The new gdc.dg/pr92216.d testcase FAILs on 32-bit Solaris/SPARC and x86 (an=
d,
I suppose, on every non-64-bit target):

+FAIL: gdc.dg/pr92216.d -O0 scan-assembler
_DT16_D7imports7pr922161B8__mixin24getSMFZPv[: \\t\\n]
+FAIL: gdc.dg/pr92216.d -O0 -frelease scan-assembler
_DT16_D7imports7pr922161B8__mixin24getSMFZPv[: \\t\\n]
+FAIL: gdc.dg/pr92216.d -O0 -frelease -g scan-assembler
_DT16_D7imports7pr922161B8__mixin24getSMFZPv[: \\t\\n]
+FAIL: gdc.dg/pr92216.d -O0 -g scan-assembler
_DT16_D7imports7pr922161B8__mixin24getSMFZPv[: \\t\\n]

Same at -O[1-3s].  While the 64-bit version contains the expected

_DT16_D7imports7pr922161B8__mixin24getSMFZPv

the 32-bit one has

_DT8_D7imports7pr922161B8__mixin24getSMFZPv

I can't tell for certain if it's enough to allow for those two variants
or if more is needed.

Btw., I noticed that binutils 2.34 c++filt -s dlang cannot demangle those
symbols.  Is this expected?=
