This can lead to warnings of unused initializations. In the attached sample code, the analyzer warns that "bc" is initialized, but not read. The output of the program correctly logs "BC". (Please forgive the extraneous bits.

[llvm-bugs] [Bug 26649] New: buggy adaptive locking case
https://llvm.org/bugs/show_bug.cgi?id=26649
Bug ID: 26649
Summary: buggy adaptive locking case
Product: OpenMP
Version: unspecified
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: P
Component: Runtime Library
Assignee: unassignedb...@nondot.org
Reporter: pawel.osmialow...@foss.arm.com

Classification: Unclassified
Hello,
In __kmp_get_user_lock_owner() function in kmp_lock.cpp I've found
following switch:
switch (seq) {
case lockseq_tas:
case lockseq_nested_tas:
return __kmp_get_tas_lock_owner((kmp_tas_lock_t *)lck);
#if KMP_HAS_FUTEX
case lockseq_futex:
case lockseq_nested_futex:
return __kmp_get_futex_lock_owner((kmp_futex_lock_t *)lck);
#endif
case lockseq_ticket:
case lockseq_nested_ticket:
return __kmp_get_ticket_lock_owner((kmp_ticket_lock_t *)lck);
case lockseq_queuing:
case lockseq_nested_queuing:
#if KMP_USE_ADAPTIVE_LOCKS
case lockseq_adaptive:
return __kmp_get_queuing_lock_owner((kmp_queuing_lock_t *)lck);
#endif
case lockseq_drdpa:
case lockseq_nested_drdpa:
return __kmp_get_drdpa_lock_owner((kmp_drdpa_lock_t *)lck);
default:
return 0;
}
Seems like '#endif' correspondig to '#if KMP_USE_ADAPTIVE_LOCKS' was
placed one line too low causing queuing and nested queuing lock cases
are currently handled by drdpa lock case function when
KMP_USE_ADAPTIVE_LOCKS is not 1.

It looks like __is_referenceable is false and unique_ptr::operator[]()
gets T as the return type instead of T&.

[llvm-bugs] [Bug 26655] New: [Thumb2] Incorrect CPSR liveness for bundled instructions
https://llvm.org/bugs/show_bug.cgi?id=26655 Bug ID: 26655 Summary: [Thumb2] Incorrect CPSR liveness for bundled instructions Product: tools Version: trunk Hardware: PC OS: Linux Status: NEW Severity: normal Priority: P Component: llc Assignee: unassignedb...@nondot.org Reporter: mgr...@codeaurora.org CC: llvm-bugs@lists.llvm.org Classification: Unclassified For Thumb2 instructions which have the CPSR and which are part of an instruction bundle, the CPSR liveness is always false. But the function UpdateCPSRUse does not recognize this and expects the liveness to be true and hence asserts: clang-3.8: /prj/llvm-arm/home/nightly/src/qc-38/llvm/lib/Target/ARM/Thumb2SizeReduction.cpp:1381: bool UpdateCPSRUse(llvm::MachineInstr &, bool): Assertion `LiveCPSR && "CPSR liveness tracking is wrong!"' failed. We need to fix this by skipping the assert for such instructions. -- You are receiving this mail because: You are on the CC list for the bug. ___ llvm-bugs mailing list llvm-bugs@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-bugs
