From 43abf42d132d75e8f51519b8c946e7a57e94175b Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Martin=20Storsj=C3=B6?= Date: Fri, 7 Oct 2016 16:44:22 +0300 Subject: [PATCH] builtins: Allow building windows arm functions for mingw When building for MSVC, the msvcrt libraries contain these functions. When building in a mingw environment, we need to provide them somehow, e.g. via compiler-rt. The divmod functions work in the same way as the corresponding __rt_*div* functions for windows, but their parameters are swapped. --- lib/builtins/CMakeLists.txt | 25 ++++++++++++++++++++++++- lib/builtins/arm/aeabi_idivmod.S | 9 +++++++++ lib/builtins/arm/aeabi_ldivmod.S | 12 ++++++++++++ lib/builtins/arm/aeabi_uidivmod.S | 9 +++++++++ lib/builtins/arm/aeabi_uldivmod.S | 12 ++++++++++++ lib/builtins/fixdfdi.c | 8 ++++++++ lib/builtins/fixsfdi.c | 8 ++++++++ lib/builtins/fixunsdfdi.c | 8 ++++++++ lib/builtins/fixunssfdi.c | 8 ++++++++ lib/builtins/floatdidf.c | 8 ++++++++ lib/builtins/floatdisf.c | 8 ++++++++ lib/builtins/floatundidf.c | 8 ++++++++ lib/builtins/floatundisf.c | 8 ++++++++ 13 files changed, 130 insertions(+), 1 deletion(-) diff --git a/lib/builtins/CMakeLists.txt b/lib/builtins/CMakeLists.txt index 5cbc1cb..1fc4b32 100644 --- a/lib/builtins/CMakeLists.txt +++ b/lib/builtins/CMakeLists.txt @@ -371,7 +371,30 @@ set(arm_Thumb1_SOURCES ${arm_Thumb1_VFPv2_SOURCES} ${arm_Thumb1_icache_SOURCES}) -if(NOT WIN32) +if(MINGW) + set(arm_SOURCES + fixdfdi.c + fixsfdi.c + fixunsdfdi.c + fixunssfdi.c + floatdidf.c + floatdisf.c + floatundidf.c + floatundisf.c + arm/aeabi_idivmod.S + arm/aeabi_ldivmod.S + arm/aeabi_uidivmod.S + arm/aeabi_uldivmod.S + divmoddi4.c + divmodsi4.c + divdi3.c + divsi3.c + moddi3.c + udivmoddi4.c + udivmodsi4.c + udivsi3.c + umoddi3.c) +else(MINGW) # TODO the EABI sources should only be added to EABI targets set(arm_SOURCES ${arm_SOURCES} diff --git a/lib/builtins/arm/aeabi_idivmod.S b/lib/builtins/arm/aeabi_idivmod.S index 2fcad86..5dab937 100644 --- a/lib/builtins/arm/aeabi_idivmod.S +++ b/lib/builtins/arm/aeabi_idivmod.S @@ -15,12 +15,21 @@ // return {quot, rem};
