Bug ID: 83109 Summary: [CET] improper code generation for builtin_longjmp with -fcf-protection -mcet Product: gcc Version: 8.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: target Assignee: unassigned at gcc dot gnu.org Reporter: igor.v.tsimbalist at intel dot com Target Milestone: --- As inssp instruction adust the shadow stack pointer (ssp) only by value in the range of [0..255] there should be a loop generated to adjust ssp if the value greater then 255. Currently builtin_longjmp does one time adjustment with incssp.
