Petter Reinholdtsen 5100825c51 Only use __int128 on architectures where it is present. 
With GCC and Clang, look for the __SIZEOF_INT128__ define only defined
when __int128 is present before trying to use it.

This fixes build problem on all 32 bit Linux architectures.

Mahesh Madhav cfd526afd0 Fix strict aliasing violations 
The cast to char** is a violation of strict aliasing rules.
Compilers may generate incorrect code due to this issue.
Using memcpy to avoid the issue. Not expecting perf difference.

Matt Liberty cd9d9fcc13 Fix namespace build of zlib gzguts.h on macOS 
Move ABC_NAMESPACE_HEADER_START (and the abc_global.h include) before the
non-LFS prototype block so the bare gzFile references in gzopen64/gzseek64/
gztell64/gzoffset64 resolve to the namespaced type. Without this, building
with ABC_USE_NAMESPACE=xxx fails on platforms that compile this block (e.g.
macOS, which does not define _LARGEFILE64_SOURCE):

  gzguts.h: error: unknown type name 'gzFile'; did you mean 'xxx::gzFile'?

Restores the header ordering used in the previous zlib 1.2.5 sources.

mainUtils: match readline behavior when ABC_USE_READLINE is undefined
 2026-06-05 16:14:23 +07:00
Matt Liberty 66f5d7c7a2 mainUtils: match readline behavior when ABC_USE_READLINE is undefined 
The non-readline branch of Abc_UtilsGetUsersInput has three behavioral
gaps versus the readline branch that break callers driving abc as a
coprocess over a pipe (e.g. yosys's passes/techmap/abc.cc, which spawns
"abc -s" with piped stdin/stdout and uses read_until_abc_done to wait
for "abc NN> <command>" lines):

  1. The prompt is written with fprintf() and never flushed. On a pipe
     stdout is fully buffered, so the prompt never reaches the reader.
     The reader waits for the prompt, abc waits in fgets(), deadlock.

  2. There is no echo of the line read from stdin. readline() emits
     each character to its output stream; yosys's protocol depends on
     seeing "abc NN> source ...\n" in the output to advance state.
     Without an echo it waits forever.

  3. EOF on stdin is silently ignored: fgets() returns NULL but the
     function returns a stale Prompt buffer, causing a tight loop on
     pipe close. The readline branch exit(0)s on NULL.

Fix all three. Echo only when stdin is not a tty -- on a tty the kernel
already echoes typed characters during cooked input, so double-echo
would be visible to interactive users.

Min Hsu 9e02a87c1d misc: Prevent Vec_IntRemove from loading nSize in every iteration 
This seemly benign loop
```
for ( i++; i < p->nSize; i++ )
  p->pArray[i-1] = p->pArray[i];
```

will actually load `p->nSize` in every loop iteration (rather than
memorizing the value) due to some unfortunate pointer aliasing properties
in C/C++. As Vec_IntRemove is quite ubiquitous, this extra memory load
actually causes visible performance impact and prevents further
optimizations on the loop.

This patch fixes this by factoring `p->nSize` out of the loop.
