Dear All, I would like to ask you help with the following: Assume that I have an area of 36 cells (or sub-areas) sr<-matrix(data=seq(from=1,to=36),nrow=6,ncol=6,byrow=TRUE) > sr [,1] [,2] [,3] [,4] [,5] [,6] [1,] 1 2 3 4 5 6 [2,] 7 8 9 10 11 12 [3,] 13 14 15 16 17 18 [4,] 19 20 21 22 23 24 [5,] 25 26 27 28 29 30 [6,]

In r219010, I merged integer and string fields into a single header field. By reducing the number of metadata operands used in debug info, this saved 2.2GB on an `llvm-lto` bootstrap. I've done some profiling of DW_TAGs to see what parts of PR17891 and PR17892 to tackle next, and I've concluded that they will be insufficient. Instead, I'd like to implement a more aggressive plan,
