When bringing up the runtime on a new architecture, this can be quite broken early on (including mesed up memory allocation, etc). In those situations, jl_ (along with regular printf) is an indispensible tool. However, it was assuming that variables are already initialized and crashed during very early bootstrap when this wasn't the case. Add some extra checks to make it a bit more robust.
Would have caught some bringup mistakes that cost me a bunch of time today.
* Remove `jl_dlsym_e()` to instead be rolled into `jl_dlsym()` with a `throw_err` parameter, similar to `jl_load_dynamic_library()`. * Fix #28881 by having `Libdl.dlsym()` return `nothing` on missing symbol, rather than `C_NULL`.
This changes `dlopen()` to mimic `dlsym()` so that a negative result returns `nothing`. While not necessary in the same way as in the `dlsym()` case (there are no valid `NULL` `dlopen()` results) the consistency is worth it.
* Fix type signature of mul! methods for multiplying SparseMatrixCSCs with Diagonal matrices. Type signature for diagonal matrices was wrong, causing fallback to generic Matmul. * Add SparseMatrixCSC*Diagonal dispatch test * Fix trailing whitespace * Don't copy with deepcopy
#29044) The code for this expected the first element of a block to be a line number; check to make sure it is before using it.
cp() doc : dest->dst
* work around a splatting penalty in twiceprecision * add allocation test

In this case, the result of `iterate` has not been checked for
`nothing`, so we try to call `indexed_iterate` (for destructuring
assignment) on a Union of Nothing and the tuple returned by
`iterate`. That has two method matches, and so was excluded from
constant propagation. This commit fixes that by generalizing the
constant prop heuristic from requiring one method match to
requiring one non-Bottom method match.
This issue caused a large slowdown in DelimitedFiles, where
the inner loop consists of
```
while idx <= slen
val,idx = iterate(dbuff, idx)
```
There is no need to fetch the next state after the last element.
The design taken here is that CFG transformations are allowed during compacting, but BBs are only removed (i.e. BB numbers are only changed at the beginning of compaction).
* Adding text on how to embed Julia on Windows. * Fixed trailing whitespace.
