Description Josh Coopman 2021-06-24 13:24:12 UTC 
Description of problem:
Customer is seeing some large performance differences when compiling/assembling certain code from toolset6 vs. toolset10.  The code assembles in around 25 seconds on toolset6 and about 29 minutes on toolset10.  They did some research and found a bugfix that they thought applied:

https://sourceware.org/bugzilla/show_bug.cgi?id=26406

They compiled in the fix and showed an improvement down to 23 seconds with the binutils they patched from toolset10.  They'd like this put in an updated binutils package.


Version-Release number of selected component (if applicable):

How reproducible:
