Moved some patterns and observed that some patterns ICEs for Long Double and Float patterns. The patterns which does the operations are:- /* Simplify sqrt(x) * sqrt(y) -> sqrt(x*y). */ (for root (SQRT CBRT) (simplify (mult (root:s @0) (root:s @1)) (root (mult @0 @1 /* Simplify pow(x,y) * pow(x,z) -> pow(x,y+z). */ (simplify (mult (POW:s @0 @1) (POW:s @0 @2)) (POW @0 (plus @1 @2))) /* Simplify expN(x) * expN(y) -> expN(x+y). */ (for expss (EXP EXP2 EXP10 POW10) (simplify (mult (exps:s @0) (exps:s @1)) (exps (plus @0 @1 /* Simplify x / expN(y) into x*expN(-y). */ (for expss (EXP EXP2 EXP10 POW10) (simplify (rdiv @0 (exps:s @1)) (mult @0 (exps (negate @1) All the operations in the attached testcase results in SEG FAULT:- aarch64-thunder-elf-gcc simlify-2.c -O2 -funsafe-math-optimizations -lm

[Bug middle-end/67285] New: ICE with (rdiv (POW:s @0 REAL_CST@1) @0)
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=67285
Bug ID: 67285
Summary: ICE with (rdiv (POW:s @0 REAL_CST@1) @0)
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: middle-end
Assignee: unassigned at gcc dot gnu.org
Reporter: hs.naveen2u at gmail dot com
Target Milestone: ---
The following pattern should work as expected:-
+ /* Simplify pow(x,c) / x -> pow(x,c-1). */
+ (simplify
+ (rdiv (POW:s @0 REAL_CST@1) @0)
+ (if (!TREE_OVERFLOW (@1))
+ (POW @0 (minus @1 { build_one_cst (type); }
However, it generates the following error:-
internal compiler error: tree check: expected ssa_name, have var_decl in
simplify_builtin_call, at tree-ssa-forwprop.c:1259
Its due to REAL_CST@1
