2 # If we need to download a custom MinGW, do so here and set the path
5 # Here we also do a pretty heinous thing which is to mangle the MinGW
6 # installation we just downloaded. Currently, as of this writing, we're using
7 # MinGW-w64 builds of gcc, and that's currently at 6.3.0. We use 6.3.0 as it
8 # appears to be the first version which contains a fix for #40546, builds
9 # randomly failing during LLVM due to ar.exe/ranlib.exe failures.
11 # Unfortunately, though, 6.3.0 *also* is the first version of MinGW-w64 builds
12 # to contain a regression in gdb (#40184). As a result if we were to use the
13 # gdb provided (7.11.1) then we would fail all debuginfo tests.
15 # In order to fix spurious failures (pretty high priority) we use 6.3.0. To
16 # avoid disabling gdb tests we download an *old* version of gdb, specifically
17 # that found inside the 6.2.0 distribution. We then overwrite the 6.3.0 gdb
18 # with the 6.2.0 gdb to get tests passing.
20 # Note that we don't literally overwrite the gdb.exe binary because it appears
21 # to just use gdborig.exe, so that's the binary we deal with instead.
23 # Otherwise install MinGW through `pacman`
