2019-09-03compiler: only import variable into . if same packageIan Lance Taylor2-2/+2
If we dot-import a package, we should only add an imported variable to the package bindings if the variable is in the package being imported. A test case for this is the 1.13 os package, in which ErrClosed and friends are defined both locally and in the imported internal/oserror package.

The new sigfpe-eh.c fails with internal compiler error: RTL check: expected elt 0 type 'e' or 'u', have 'w' (rtx const_int) This is most likely due to a typo: XEXP (*op1, 0) was used, when XEXP (*op0, 1) was intended.

This test uses a call-saved register as a global variable. It attempts to preserve its value across main, but only the lower int part is preserved, which is not good enough for x86_64, when the runtime that calls main() happens to hold something in the chosen register that is not a zero-extension from the 32-bit value, and rightfully expects the full register to remain unchanged when main() returns. for gcc/testsuite/ChangeLog * gcc.target/i386/20020616-1.c: Preserve full register across main.

2019-08-31or1k: Fix issue with set_got clobbering LR (r9)Stafford Horne4-2/+15
When compiling glibc we found that the GOT register was being allocated r9 when the instruction was still set_got_tmp. That is a problem because r9 is the Link Register (LR) in OpenRISC which is used/clobbered in set_got. We cannot use r9 as the GOT register. Also, we cannot simply say set_got_tmp clobbers r9 as this is the reason for having the temporary set_got_tmp. Fix by using a register class constraint that does not allow r9 during register allocation. gcc/ChangeLog: * config/or1k/constraints.md (t): New constraint. * config/or1k/or1k.h (GOT_REGS): New register class. * config/or1k/or1k.md (set_got_tmp, set_got): Use t contraint.

2019-08-31compiler: check for notinheap struct at each struct fieldIan Lance Taylor2-26/+26
When generating write barriers, we were only checking for a notinheap struct at the outermost struct. That mishandled the case of setting a pointer to a notinheap struct as a field of another struct that is not notinheap. This caused an invalid write barrier error when building the 1.13 version of the runtime. Reviewed-on: https://go-review.googlesource.com/c/gofrontend/+/192279 From-SVN: r275240
2019-08-31compiler, runtime: support and use single argument go:linknameIan Lance Taylor5-9/+38
The gc compiler has started permitting go:linkname comments with a single argument to mean that a function should be externally visible outside the package. Implement this in the Go frontend. Change the libgo runtime package to use it, rather than repeating the name just to export a function. Remove a couple of unnecessary go:linkname comments on declarations.
