Bug ID: 27565
Summary: ld: Support input section description keyword: REVERSE
Product: binutils
Version: unspecified
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: ld
Assignee: unassigned at sourceware dot org
Reporter: i at maskray dot me
Target Milestone: ---
REVERSE complements SORT, e.g.
SECTIONS { .aaa : { *(REVERSE(SORT_BY_NAME(.aaa.*))) } }
If the user wants to detect some static initialization order fiasco issues,
they can specify:
# If https://sourceware.org/bugzilla/show_bug.cgi?id=26404 is supported,
# the user can provide a fragment instead of a full linker script
.init_array : {
*(SORT_BY_INIT_PRIORITY(REVERSE(.init_array.* .ctors.*)))
*(REVERSE(.init_array EXCLUDE_FILE (*crtbegin.o *crtbegin?.o *crtend.o
*crtend?.o ) .ctors))
}
which runs static constructors in a reversed order.
