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 (and,
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?

That discrepancy is the encoded this pointer offset. I didn't consider that
this information was present when I added the test.

Yes, these thunk symbols are a non-standard extension.

FYI, I checked on avr-elf as well, and the symbol is:
