Appendix B. Changes in Version 10.1
The sections below document features and bug fixes introduced in Red Hat Developer Toolset 10.1.
B.1. Changes in GCC

One of the most notable bug fixes is:
gcc-gfortransubpackage did not include the
libgfortran_nonshared.astatic library. As a consequence, linking a program was not always successful because several symbols were missing. With this update, the
devtoolset-10-gcc-gfortranpackage now contains the
libgfortran_nonshared.alibrary and the program can be linked successfully.
B.2. Changes in elfutils
Red Hat Developer Toolset 10.1 is distributed with elfutils 0.182.
Numerous bug fixes and new features have been added since the previous release of Red Hat Developer Toolset:
New features added to the

- A new thread-busy metric and more detailed error metrics.
--fdcache-mintmpoption and file system free space tracking.
- Increased web API concurrency while grooming.
- More efficient package traversal,
New features added to
- Compressed kernel ELF images are now supported.
DEBUGINFOD_SONAMEmacro has been added to
debuginfod.h. This macro can be used with the

The following features have been added or modified since the previous release of Red Hat Developer Toolset:
- Performance and stability improvements to user-space probing.
- Users can now access implicit thread local storage variables on these architectures: AMD64, Intel 64, IBM Z, the little-endian variant of IBM Power Systems.
- Initial support for processing of floating point values.
- Improved concurrency for scripts using global variables. The locks required to protect concurrent access to global variables have been optimized so that they span the smallest possible critical region.
- New syntax for defining aliases with both a prologue and an epilogue.
syscallarguments are writable again.
