Exit if memory allocation keeps failing, instead of looping forever 2025-06-13 14:11:03 +02:00
Ralf Gommers 765ad8bcd2 Fix guard around `alloc_hugetlb`, fixes compile warning 
The warning was:
```
/home/rgommers/code/pixi-dev-scipystack/openblas/OpenBLAS/driver/others/memory.c: At top level:
/home/rgommers/code/pixi-dev-scipystack/openblas/OpenBLAS/driver/others/memory.c:2565:14: warning: 'alloc_hugetlb' defined but not used [-Wunused-function]
 2565 | static void *alloc_hugetlb(void *address){
      |              ^~~~~~~~~~~~~
```

The added define is the same as is already present in the TLS part of
`memory.c`. This follows up on gh-4681.

Ralf Gommers 48caf2303d Fix build warning about discarding volatile qualifier in memory.c 
The warning was:
```
[4339/5327] Building C object driver/others/CMakeFiles/driver_others.dir/memory.c.o
/home/rgommers/code/pixi-dev-scipystack/openblas/OpenBLAS/driver/others/memory.c: In function 'blas_shutdown':

In file included from /home/rgommers/code/pixi-dev-scipystack/openblas/OpenBLAS/common.h:83,

  482 | extern void free (void *__ptr) __THROW;
      |                   ~~~~~~^~~~~
```

The use of `volatile` for `newmemstruct` seems on purpose, and there are
more such constructs in this file. The warning appeared after gh-4451
and is correct. The `free` prototype doesn't expect a volatile pointer,
hence this change adds a cast to silence the warning.
