From 83b8d5027d2f80c4603cd706da95d6c9a09a4e16 Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Thu, 16 Dec 2021 15:26:36 -0300 Subject: malloc: Remove memusage.h And use machine-sp.h instead. The Linux implementation is based on already provided CURRENT_STACK_FRAME (used on nptl code) and STACK_GROWS_UPWARD is replaced with _STACK_GROWS_UP. --- sysdeps/unix/sysv/linux/machine-sp.h | 29 +++++++++++++++++++++++++++++ 1 file changed, 29 insertions(+) create mode 100644 sysdeps/unix/sysv/linux/machine-sp.h (limited to 'sysdeps/unix/sysv') diff --git a/sysdeps/unix/sysv/linux/machine-sp.h b/sysdeps/unix/sysv/linux/machine-sp.h new file mode 100644 index 0000000000..257d09e60d --- /dev/null +++ b/sysdeps/unix/sysv/linux/machine-sp.h @@ -0,0 +1,29 @@ +/* Machine-specific function to return the stack pointer.
