BRIG does not contain debugging information

[harald-lang]

The BRIG file distributed along with the HSAIL-Debugger does not contain debugging information. Thus, the tutorial does not work as described in https://github.com/HSAFoundation/HSA-Debugger-AMD/blob/master/TUTORIAL.md

Users have to manually assemble the matrix multiplication sample: HSAILasm -g -include-source matrixMul_kernel.hsail

This in not really an issue, but might not be intended...

Hi,
Did you try the latest bits from cd5ef1a? Please let us know if you still see an issue with that commit.

Hi,

yes, I installed the .deb files from cd5ef1a

Ah. We have only updated the matrixMul brig file (in https://github.com/HSAFoundation/HSA-Debugger-AMD/blob/master/AMDGPUKernelDebugSDK/samples/MatrixMultiplication/matrixMul_kernel.brig) with that commit.

We will update the debian package in our next update. Thanks.

[harald-lang]

Ah okay. I didn't try that one. I prefer to dpkg -i whenever possible :)

Thanks!
