Bug ID: 71489
Summary: [7 regression] gcc.dg/tree-ssa/attr-hotcold-2.c FAILs
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: testsuite
Assignee: unassigned at gcc dot gnu.org
Reporter: ro at gcc dot gnu.org
CC: hubicka at gcc dot gnu.org
Target Milestone: ---
Host: i386-pc-solaris2.*, sparc-sun-solaris2.*
Target: i386-pc-solaris2.*, sparc-sun-solaris2.*
Build: i386-pc-solaris2.*, sparc-sun-solaris2.*
Between 20160606 and 20160609, the gcc.dg/tree-ssa/attr-hotcold-2.c test
started
to error out:
+ERROR: gcc.dg/tree-ssa/attr-hotcold-2.c: error executing dg-final: syntax
error in target selector "profile_estimate"
+UNRESOLVED: gcc.dg/tree-ssa/attr-hotcold-2.c: error executing dg-final: syntax
error in target selector "profile_estimate"
This is due to a syntax error in Jan's last change:
/* { dg-final { scan-tree-dump-times 1 "hot label heuristics" 1
"profile_estimat
e" } } */
/* { dg-final { scan-tree-dump-times 1 "cold label heuristics" 1
"profile_estima
te" } } */
The first arg to scan-tree-dump times is supposed to be a regexp, not a count.
But even with that fixed, the testcase FAILs:
FAIL: gcc.dg/tree-ssa/attr-hotcold-2.c scan-tree-dump-times profile_estimate
"block 4, loop depth 0, count 0, freq [1-4][^0-9]" 1
;; basic block 4, loop depth 0, count 0, freq 2, maybe hot
;; basic block 4, loop depth 0, count 0, freq 2, maybe hot
;; basic block 4, loop depth 0, count 0, freq 2
FAIL: gcc.dg/tree-ssa/attr-hotcold-2.c scan-tree-dump-times profile_estimate
"block 5, loop depth 0, count 0, freq [6-9][0-9][0-9][0-9]" 1
;; basic block 5, loop depth 0, count 0, freq 7660, maybe hot
;; basic block 5, loop depth 0, count 0, freq 7660, maybe hot
;; basic block 5, loop depth 0, count 0, freq 7660, maybe hot
This is a regression from the gcc-6 branch.
