# Progress # * GDB is confused by the line table generated by GCC with -gcolumn-info PR 22531. [2/5] My preparatory patches are reviewed, mostly on C++, get encouraged to use more fancy C++ features.

* gfortran 7.2 vs 8.0 debug information difference. [2/5] Many gdb.fortran test fails with gfortran 8 but gfotran 7.2 is OK. I 'git bisect' gcc and find the commit causing the debug info change, it is like a bug to me, but my compiler/fortran knowledge is too few to claim it is a 7.2 -> 8.0 regression. Posted my analysis to gcc@ and fortran@ mail list.

* TCWG-1040, SVE patches review. [1/5] Review Alan's patches.

# Plan #

* PR 22531, upstream preparatory patches, * Write patch series v2 for TCWG-1292.
