+
+    RISC-V: Add and document the "-mno-relax" option
+
+    RISC-V relies on aggressive linker relaxation to get good code size.  As
+    a result no text symbol addresses can be known until link time, which
+    means that alignment must be handled during the link.  This alignment
+    pass is essentially just another linker relaxation, so this has the
+    unfortunate side effect that linker relaxation is required for
+    correctness on many RISC-V targets.
+
+    The RISC-V assembler has supported an ".option norelax" for a long time
+    because there are situations in which linker relaxation is a bad idea --
+    the canonical example is when trying to materialize the initial value of
+    the global pointer into a register, which would otherwise be relaxed to
+    a NOP.  We've been relying on users who want to disable relaxation for
+    an entire link to pass "-Wl,--no-relax", but that still relies on the
+    linker relaxing R_RISCV_ALIGN to handle alignment despite it not being
+    strictly necessary.
+
+    This patch adds a GCC option, "-mno-relax", that disable linker
+    relaxation by adding ".option norelax" to the top of every generated
+    assembly file.  The assembler is smart enough to handle alignment at
+    assemble time for files that have never emitted a relaxable relocation,
+    so this is sufficient to really disable all relaxations in the linker,
+    which results in significantly faster link times for large objects.
+
+    This also has the side effect of allowing toolchains that don't support
+    linker relaxation (LLVM and the Linux module loader) to function
+    correctly.  Toolchains that don't support linker relaxation should
+    default to "-mno-relax" and error when presented with any R_RISCV_ALIGN
+    relocation as those need to be handled for correctness.
