**【标题描述】[deja]生成的过程或目标文件中找不到预期目标字段**

**【环境信息】**

软件信息

- OS版本及分支信息:openEuler 22.03 (LTS-SP3)

- 内核信息: 5.10.0-176.0.0.89.oe2203sp3.aarch64

```

使用内建 specs。

COLLECT_GCC=gcc

COLLECT_LTO_WRAPPER=/usr/libexec/gcc/aarch64-linux-gnu/10.3.1/lto-wrapper

**【问题复现步骤】**

1. 用例double_sized_mul-1.c

```

gcc ./gcc.dg/double_sized_mul-1.c -fno-diagnostics-show-caret -fno-diagnostics-show-line-numbers -fdiagnostics-color=never -fdiagnostics-urls=never -O2 -fif-conversion-gimple -fuaddsub-overflow-match-all -fdump-tree-widening_mul-stats -S -o double_sized_mul-1.s

grep -n "double sized mul optimized: 1" double_sized_mul-1.c.198t.widening_mul

```

2.用例ifcvt-gimple.c

```

/usr/bin/gcc ./gcc.dg/ifcvt-gimple.c -fno-diagnostics-show-caret -fno-diagnostics-show-line-numbers -fdiagnostics-color=never -fdiagnostics-urls=never -O2 -fif-conversion-gimple -fdump-tree-optimized -S -o ifcvt-gimple.s

grep -n "if (optimizable" ifcvt-gimple.c.240t.optimized

grep -n "if" ifcvt-gimple.c.240t.optimized

grep -n "else" ifcvt-gimple.c.240t.optimized

grep -n "<<" ifcvt-gimple.c.240t.optimized

grep -n "<< 10;" ifcvt-gimple.c.240t.optimized

```

**【实际结果】**

1.用例double_sized_mul-1.c:未扫描到,实际需要扫描到6次


2.用例ifcvt-gimple.c:(5个失败分别为: a.不需要扫描到,实际扫描2次；b.需要扫描到2次,实际扫描到4次；c.需要扫描到2次,实际扫描到4次；d.需要扫描到1次,实际未扫描到；e.需扫描到,实际未扫描到)
