Andrew and I independently noted the long unconditional branch sequence
was using the "call" pseudo op. Technically it works, but it's a bit
odd. This patch flips it to use the "jump" pseudo-op.
This was tested with a hacked-up local compiler which forced all
branches/jumps to be long
Hi Harald and Bernhard,
Indeed, you are right about the space. However, the compile is intentional.
This catches the fix:
! { dg-final { scan-tree-dump-times "co._data1_length = 10;" 1 "original" }
}
Also, it helps to get the PR number right!

Example:
The updated test cases still reproduce the bugs with old compilers.
gcc/testsuite/
* gcc.c-torture/compile/pc44485.c (func_21): Add missing cast.
* gcc.c-torture/compile/pr106101.c: Use builtins to avoid
calls to undeclared functions. Change type of yyvsp to
char
These changes are assumed not to interfere with the test objective,
but it was not possible to reproduce the historic test case failures
(with or without the modification here).
gcc/testsuite/
* gcc.c-torture/compile/2105-1.c: Add missing int return type.
Call __builtin_exit
Add -std=gnu89 to some tests which evidently target C89-only language
features.
gcc/testsuite/
* gcc.c-torture/compile/920501-11.c: Compile with -std=gnu89.
* gcc.c-torture/compile/920501-23.c: Likewise.
* gcc.c-torture/compile/920501-8.c: Likewise.

Thanks Richi point it out.
I found this patch can't make conditional gather load succeed on SLP.
I am considering change MASK_LEN_GATHER_LOAD in pattern recognization:
If no condition mask, in tree-vect-patterns.cc, I build MASK_LEN_GATHER_LOAD
(ptr, offset, scale, 0) -> 4 arguments same as
