Previously, we were using srcDir, which would apply the wrong module dependencies (including the wrong 'replace' and 'exclude' directives) when locating an import path within a module.

When compiling for GOARCH=386 GOOS=android, the compiler was attaching R_TLS_LE relocations inappropriately -- as of Go 1.13 the TLS access recipe for Android refers to a runtime symbol and no longer needs this type of relocation (which was causing a crash when the linker tried to process it). Updates #29674. Fixes #34788.

n.Opt() is used in walkCheckPtrArithmetic to prevent infinite loops. The fact that it's used today because n.Opt() is not used for OCONVNOP during walk.go. If that changes, then it's not safe to repalce it anymore. So doing hard fail if that case happens, the author of new changes will be noticed and must change the usage of n.Opt() inside walkCheckPtrArithmetic, too.

The asm encoder generally assumes that the lowest 5 bits of the REG_XX constants match the machine instruction encoding, i.e. the lowest 5 bits is the register number. This was not true for FCR registers and M registers. Make it so. MOV Rx, FCRy was encoded as two machine instructions. The first is unnecessary. Remove.

"declared and not used" is technically correct, but might confuse the user. Switching "and" to "but" will hopefully create the contrast for the users: they did one thing (declaration), but not the other --- actually using the variable. This new message is still not ideal (specifically, declared is not entirely precise here), but at least it matches the other parsers and is one step in the right direction.

In the second step of make.bash, cmd/dist builds cmd/go by invoking the compiler, linker, and other tools directly on transitive dependencies of cmd/go. Essentially, cmd/dist acts as a minimal version of 'go install' when building go_toolchain. Until now, cmd/go has had no transitive dependencies in vendor directories. This changes in CL 202698, where several packages are deleted and equivalent versions in golang.org/x/mod are used instead. So this CL adds support to cmd/dist for vendor directories.

If a compilation has multiple text sections, code in textOff must compare the offset argument against the range for each text section to determine which one it is in. The comparison looks like this: if uintptr(off) >= sectaddr && uintptr(off) <= sectaddr+sectlen If the off value being compared is equal to sectaddr+sectlen then it is not within the range of the text section but after it.
