Bug ID: 15293
Summary: ARM codegen ice - expected larger existing stack
allocation
Product: libraries
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: Backend: ARM
Assignee: unassignedbugs at nondot.org
Reporter: arathorn at fastwebnet.it
CC: llvmbugs at cs.uiuc.edu
Classification: Unclassified
Can be reproduced using llc on the following:
; ModuleID = 'bugpoint-reduced-simplified.bc'
target datalayout =
"e-p:32:32:32-S64-i1:8:8-i8:8:8-i16:16:16-i32:32:32-i64:64:64-f16:16:16-f32:32:32-f64:64:64-f128:128:128-v64:64:64-v128:64:128-a0:0:64-n32"
target triple = "arm--linux-gnueabihf"
%"armbug.Rebindable!(TimeZone).Rebindable" = type <{ i8 }>
%armbug.SysTime = type <{ %"armbug.Rebindable!(TimeZone).Rebindable" }>
%armbug.TimeZone = type { i8* }
declare fastcc void
@opAssign(%"armbug.Rebindable!(TimeZone).Rebindable"*,
%"armbug.Rebindable!(TimeZone).Rebindable"* byval)
define fastcc %armbug.SysTime* @doOpAssign(%armbug.SysTime*
%.this_arg, %armbug.SysTime* byval %p_arg) {
entry:
br i1 undef, label %noassert, label %assert
assert: ; preds = %entry
unreachable
noassert: ; preds = %entry
call fastcc void
@opAssign(%"armbug.Rebindable!(TimeZone).Rebindable"* undef,
%"armbug.Rebindable!(TimeZone).Rebindable"* byval undef)
ret %armbug.SysTime* %.this_arg
}
and results in:
Assertion failed: (size >= excess && "expected larger existing stack
allocation"), function HandleByVal, file ARMISelLowering.cpp, line 1681.
