2d622a |
New features
|
|
Packit |
2d622a |
|
|
Packit |
2d622a |
* Partial segment remapping. This allows non-relinked binaries to try
|
|
Packit |
2d622a |
to take advantage of libhugetlbfs' segment remapping code. Large
|
|
Packit |
2d622a |
segments are required, especially on Power. This feature is useful
|
|
Packit |
2d622a |
for estimating huge page performance, however full relinking will
|
|
Packit |
2d622a |
still perform better.
|
|
Packit |
2d622a |
* Add extra debugging for binaries that may run out of address space.
|
|
Packit |
2d622a |
* Log library version when HUGETLB_VERBOSE is enabled.

Packit |
2d622a |
* Rework PLT detection to work better on Power.
|
|
Packit |
2d622a |
* Add per-target-arch syscall stubs to the library. These provide
|
|
Packit |
2d622a |
reliable error messages from elflink.c if they occur while the
|
|
Packit |
2d622a |
program segments are unmapped.
|
|
Packit |
2d622a |
* Add proper SONAME to shared libs.

Packit |
2d622a |
* Sharing of writable segments is no longer possible, due to address

Packit |
2d622a |
space randomization on x86_64 (although similar issues could happen on
|
|
Packit |
2d622a |
any architecture).
