Summary: tree check failure inlining pure function
Product: new-bugs
Version: unspecified
Platform: Other
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: new bugs
AssignedTo: unassignedbugs at nondot.org
ReportedBy: baldrick at free.fr
CC: llvmbugs at cs.uiuc.edu
This testcase
__inline__ __attribute__ ((__pure__)) int g (void) {}
void f (int k) { k = g (); }
crashes llvm-gcc at -O2 on x86-32 linux:
$ gcc -c -O2 dwv.c
dwv.c: In function 'f':
dwv.c:2: internal compiler error: tree check: expected tree that contains 'decl
with visibility' structure, have 'parm_decl' in declare_return_variable, at
tree-inline.c:1271
Curiously the compiler doesn't crash on x86-64 linux. However
I see the same failing tree check for several Ada testcases on
x86-64 which pass happily on x86-32.
The relevant code snippet is:
/* LLVM LOCAL begin */
#ifdef ENABLE_LLVM
/* The return node can suddenly become multiple assignment. Because of
this
* conservatively don't consider this thing for SSA form anymore.
*/
if (DECL_P (var))
DECL_GIMPLE_FORMAL_TEMP_P (var) = 0;
#endif
/* LLVM LOCAL end */
The check fails on the assignment.
