Re: [PATCHv2][ARM] -mpure-code option for ARM

Hi Andre, I can't see new testsuite files in trunk : gcc.target/arm/pure-code/ffunction-sections.c gcc.target/arm/pure-code/no-literal-pool.c gcc.target/arm/pure-code/pure-code.exp It seems you forgot to include them in your patch. Can you post a new one with those files ? Regards Mickael On

Re: [PATCH][ARM] -mpure-code option for ARM

Hi Andre, I think you have a typo in your patch. I need to change : +text_section->unnamed.data = "\t.section .text,\"0x2006\",%%progbits"; into +text_section->unnamed.data = "\t.section .text,\"0x2006\",%progbits"; to make it works. Regards Mickael On 06/30/2016 04:32 PM

Re: [PATCH][ARM] -mpure-code option for ARM

Hi Andre, Another feedback on your purecode patch. You have to disable casesi pattern since then it will generate wrong code with -mpure-code option. Indeed it will generate an 'adr rx, .Lx' (aka 'subs rx, PC, #offset') which will not work in our case since 'Lx' label is put in an .rodata sect
