Subject: ymm register error
Date: Tue, 17 Jul 2018 11:44:00 -0000 [thread overview]
Message-ID: <DB6PR0501MB23733695073ADC48984C9F96E55C0@DB6PR0501MB2373.eurprd05.prod.outlook.com> (raw)
When trying to run gdb server on a skylake-x HEDT platform (i9-7940X) I encounter the following error:
regcache.c:264: A problem internal to GDBserver has been detected.
Unknown register ymm0h requested
From what I can tell from furious googling is that the ymm registers have changed location from broadwell-e to skylake-x.
I can see references to the ymm registers in gdb's codebase, with apparent positioning related to features like org.gnu.gdb.i386.avx & org.gnu.gdb.i386.avx512.
Being a complete novice around gdb's codebase, I'm not sure if I need to enable or state something at configure stage so that the right ymm register location is referenced.
gdb server 8 in ubuntu bionics repos works OK on the skylake-x platform, but when I compile myself it does not.
Is there something specific I need to be stating at compile time to "get" gdbserver 8 to work on skylake-x
Paul
