Subject: [PATCH] m4/stack-direction: RISC-V stack grows downward
|
||
|
|
|
||
|
|
While commit 671b2528b55c57eda1a8fe5872ff1ef61014235f ("Improve
|
||
|
|
support for Linux/RISC-V") adds some support for the RISC-V
|
||
|
|
architecture, it doesn't update m4/stack-direction.m4 to properly
|
||
|
|
support cross-compiling libsigsegv for a RISC-V architecture.
|
||
|
|
|
||
|
|
According to
|
||
|
|
https://riscv.org/wp-content/uploads/2015/01/riscv-calling.pdf: "In
|
||
|
|
the standard RISC-V calling convention, the stack grows downward", so
|
||
|
|
let's update m4/stack-direction.m4 accordingly.
