--- Comment #6 from Zhiyuan Lv <zhiyuan.lv at linux dot intel.com> --- (In reply to H.J. Lu from comment #5) > Created attachment 16083 [details] > A patch to add --unique-pushsection and .pushuniquesection > > Try this. Hi H.J, the patch works nicely with my simple test case, but still did not get expected result while trying with Linux kernel build. I did some investigation and found it to be related to "-fpatchable-function-entry=16,16". If I add this gcc option to compile test.c, the relocation entry for .alt_section is combined, causing the section dependencies again. I checked the section names of test.o with and without "patchable-function-entry". without the parameter, section names are: ".alt_section.text.foo1" ".alt_section.text.foo2" with the parameter, section name is: "alt_section__patchable_function_entries" And, another thing weird is that: the macro is used in functions foo2 and foo3, but the alt_function name suffix is "foo1"/"foo2". Could that be a hint? BTW, thanks much for the very prompt patches! Appreciate that! -- You are receiving this mail because: You are on the CC list for the bug.
