Bug ID: 19085
Summary: ldbl-128 lrintl, lroundl missing exceptions for 32-bit
long
Product: glibc
Version: 2.22
Status: NEW
Severity: normal
Priority: P2
Component: math
Assignee: unassigned at sourceware dot org
Reporter: jsm28 at gcc dot gnu.org
Target Milestone: ---
The ldbl-128 implementations of lrintl and lroundl miss "invalid" exceptions on
systems with 32-bit long for arguments that overflow long but have exponent
below 48. E.g., for MIPS64 n32:
Failure: lrint (0x1p31): Exception "Invalid operation" not set
Failure: lrint (0x1p32): Exception "Invalid operation" not set
Failure: lrint (0x1p33): Exception "Invalid operation" not set
Failure: lrint (-0x1p32): Exception "Invalid operation" not set
Failure: lrint (-0x1p33): Exception "Invalid operation" not set
Failure: lrint_downward (0x1p31): Exception "Invalid operation" not set
Failure: lrint_downward (0x1p32): Exception "Invalid operation" not set
Failure: lrint_downward (0x1p33): Exception "Invalid operation" not set
Failure: lrint_downward (-0x1p32): Exception "Invalid operation" not set
Failure: lrint_downward (-0x1p33): Exception "Invalid operation" not set
Failure: lrint_towardzero (0x1p31): Exception "Invalid operation" not set
Failure: lrint_towardzero (0x1p32): Exception "Invalid operation" not set
Failure: lrint_towardzero (0x1p33): Exception "Invalid operation" not set
Failure: lrint_towardzero (-0x1p32): Exception "Invalid operation" not set
Failure: lrint_towardzero (-0x1p33): Exception "Invalid operation" not set
Failure: lrint_upward (0x1p31): Exception "Invalid operation" not set
Failure: lrint_upward (0x1p32): Exception "Invalid operation" not set
Failure: lrint_upward (0x1p33): Exception "Invalid operation" not set
Failure: lrint_upward (-0x1p32): Exception "Invalid operation" not set
Failure: lrint_upward (-0x1p33): Exception "Invalid operation" not set
Failure: lround (0x1p31): Exception "Invalid operation" not set
Failure: lround (0x1p32): Exception "Invalid operation" not set
Failure: lround (0x1p33): Exception "Invalid operation" not set
Failure: lround (-0x1p32): Exception "Invalid operation" not set
Failure: lround (-0x1p33): Exception "Invalid operation" not set
Failure: lround_downward (0x1p31): Exception "Invalid operation" not set
Failure: lround_downward (0x1p32): Exception "Invalid operation" not set
Failure: lround_downward (0x1p33): Exception "Invalid operation" not set
